AMD B550 ChipsetFor almost a year, anyone wanting to build a new 3rd-gen Ryzen system with PCI Express 4.0 support had to opt for one of the relatively pricey X570-based boards. Now that the AMD B550 chipset is available – and along with it a very wide range of motherboards in all shapes and sizes from the usual manufacturers –  you have a lot more choices.

Since it’s a more affordable chipset, some features have been cut from the B550 compared to the X570. You get no PCIe Gen4 support directly from the chipset (only via the CPU), fewer USB 3.1 Gen2 ports, and no SLI. It’s essentially an upgraded B450 chipset, which is still a viable option, although these boards will likely be phased out in favor of B550 models eventually.

One of the main benefits of choosing a B550 motherboard over a previous-gen chipset is, of course, PCIe 4 and the improved storage performance that the new interface offers. But perhaps even more importantly, you get guaranteed compatibility with Ryzen 4000 (Zen 3). On the downside, you lose backward compatibility with previous-gen Ryzen CPUs and APUs (including the 3000-series APUs).

The Best Value AMD B550 Motherboards – ATX, mATX, mITX

Another major advantage of the B550 platform is that it’s – on average – a more affordable alternative to X570. A few B550 boards are nevertheless quite expensive and feature-packed, but because of the reduced I/O, it’s usually not a great idea to spend more than $300 on a B550 board. If you are looking for a premium 3rd-gen+ AMD Ryzen board with lots of features and connectivity, you are probably better off with one of the X570 alternatives.

With that said, these boards are some of our favorites from a value perspective (cost/feature set) in the different form factors:

At an MSRP of $179, the Gigabyte B550 Aorus Pro offers a comprehensive set of features that surpasses most entry-level X570 boards except for the additional PCIe 4.0 capability. Unlike the cheaper B550 boards, the Aorus Pro comes with a very competent VRM that runs cool and improves your chances of a stable overclock. You also get 2.5 Gbps LAN and, of course, PCIe Gen4 bandwidth for a single GPU and M.2 SSD.

The mATX form factor shaves off a few expansion slots, usually in exchange for a lower price. While the ASUS Prime B550M-A WiFi may not be an overclocker’s dream, it offers a solid foundation for a mid-range build with Gen4 GPU and M.2 bandwidth, plus an extra Gen3 M.2 slot. There is also a Prime B550M-K version without the Intel Wi-Fi module (and also without a VRM heatsink) for about $15 less.

If you are looking to build a small form-factor gaming PC based on a B550 Mini-ITX board, you have fewer options – and most are found in the semi-premium category. The Asus ROG Strix B550-I Gaming (review here) is the only B550 ITX motherboard from Asus, but it’s a very attractive model with a reinforced PCIe 4.0 x16 slot, integrated Wi-Fi and 2.5Gbps LAN.

*There is also an (as of yet unavailable) Prime B550M-K model, which is the cheapest Asus board with a lesser VRM setup but otherwise similar to the B550M-A.

ASUS ROG STRIX B550-E GAMING

The ROG Strix B550-E Gaming is Asus’ flagship B550 board and one of few to support SLI. Both of the two full-size PCIe slots are reinforced, so you don’t have to worry about GPU sag with either card. There are two M.2 slots and both of them come with heatsinks. Naturally, the Strix B550-E has the same chipset limitations as every other B550 motherboard, so only one will run at PCIe Gen4 speed while the other supports Gen3.

ASUS ROG Strix B550-E Gaming

Being a premium B550 alternative, this Republic of Gamers board is almost as expensive as the X570 board with the same name. This could make it a tough sell, as the X570-E offers a similarly extensive feature set in addition to the better I/O provided by the chipset. If you don’t need the latter, the B550-E is nevertheless a slightly more affordable alternative. It comes with a strong 14+2-phase VRM that should offer good overclocking possibilities even with the most demanding Ryzen chips like the Ryzen 9 3950X. There’s also plenty of RGB, VRM heatsinks, AIO pump header, fanless PCH cooling, and a BIOS Flashback button.

ASUS ROG STRIX B550-F GAMING

The B550-F strongly resembles the B550-E but is considerably less expensive (about $70 less). This fact alone makes this board much more interesting for builders looking for a more affordable option to X570. Some compromises have to be made, obviously. There’s no SLI support, WiFi is optional (see below), and the VRM is somewhat less sophisticated. Also, only the top PCIe x16 slot is reinforced, which is reasonable considering the lack of SLI support.

Asus ROG Strix B550-F Gaming

Most of the other details remain the same, however. The B550-F comes with the same VRM heatsinks, AIO pump header, fanless PCH cooling, and BIOS Flash button. It also offers the same 2.5 GbE and USB 3.2 connectivity and dual M.2 slots, in addition to a premium audio chip.

ASUS ROG STRIX B550-F GAMING (WiFi)

This model is nearly identical to the above board, but comes with the same AX200 Wi-Fi solution as the B550-E and costs a bit more.

Asus B550-F WiFi

ASUS ROG STRIX B550-I GAMING

This is a somewhat premium-oriented ITX motherboard with the same striking ROG Strix design as the aforementioned full-size ATX models. As this is a much smaller form factor, you are limited to 2 DIMM slots and a single PCIe slot that is reinforced for better graphics card support.

Even though this is a smaller board, there are still 2 M.2 slots. One is above the PCIe slot and comes with a heatsink, while the other one is on the back of the motherboard and does not come with a heatsink. As usual, only one PCIe Gen4 SSD is supported, and if you install another one on the back it will run at Gen3 speed.

Asus ROG Strix B550-i Gaming

The Strix B550-I shares many features with the B550-E, including 2.5 GbE and AX200 WiFi, but the 8+2-phase VRM has more in common with the lower-end boards. All things considered, this is an ideal motherboard is you are interested in building a small form factor PC that does not compromise on power. On the downside, it’s quite expensive.

ASUS TUF GAMING B550-PLUS

Asus’ TUF series is wedged between the Strix and Prime lineups in terms of pricing and feature sets. Here we have the Asus TUF Gaming B550-PLUS that comes in black and grey with white and yellow accents. This is an ATX board so you get the usual 4 DIMM slots and 2 PCIe slots, with the top one being reinforced to prevent GPU sag. There are two M.2 slots but only the bottom one comes with a heatsink.

Asus TUF Gaming B550-Plus

This is a value-oriented motherboard, so the VRM is scaled back to an 8+2 design. You still get 2.5 Gbit LAN, VRM heatsinks, AIO pump header, fanless PCH cooling, and BIOS Flashback.

ASUS TUF GAMING B550M-PLUS

This model is similar to the B550-Plus but this is a MATX motherboard so it’s smaller and you only get two PCIe slots. You do get the same 4 DIMM slots with the same high memory OC options as the more expensive boards. There are two M.2 slots and the bottom one comes with a heatsink.

Asus TUF Gaming B550M Plus

The TUF B550M-Plus has however not been scaled down in the VRM department. It has 8+2 DrMOS power stages with sizeable heatsinks – a solution identical to the full-size ATX version. Another highlight is the same Realtek 2.5 GbE LAN controller is also included.

ASUS TUF GAMING B550M-PLUS (Wi-Fi)

As the name implies, this is the same board as the above but with an Intel AX200 WiFi adapter. Asus TUF Gaming B550M Plus WiFi

ASUS PRIME B550-PLUS

The Prime series is at the budget end of Asus’ recent motherboard lineups. While there are several varieties of the micro-ATX Prime B550, your ATX options are restricted to this model.

ASUS Prime B550-Plus

Unsurprisingly, some features had to go to keep the price tag to a minimum. You will have to settle for a 1 GbE Realtek LAN adapter, the VRM heatsinks are smaller and there are no integrated M.2 heatsinks. However, you get the same RAM support as with the more expensive boards, a reinforced GPU slot, USB 3.2 Gen2 connectivity, and dual M.2 SSD slots.

Reviews: No reviews available at this time.
ASUS PRIME B550M-A WiFi

This motherboard is available in several flavors that are all very nearly identical. There are two different WiFi options – the B550M-A AC (with AC-class WiFi support, and the B550M-A Wifi (listed here, with Intel AX200 WiFi) – as well as two editions without wireless connectivity, including the B550M-A and the B550M-K (the latter of which has a cheaper VRM).

Asus Prime B550M-A WiFi

Regardless of your choice, this is a pretty barebones motherboard with very little cooling on board. The GPU slot is not reinforced and there are no heatsinks for the M.2 slots – but you do get two of them. Cutbacks have also been made in the VRM department, where Asus has opted for a 4+4 design (4+2 in the B550M-K). USB 3.2 Gen2 connectivity is available, but only via two Type-A ports.

GIGABYTE B550 AORUS MASTER

The B550 Aorus Master is one of the higher-end B550 models that’s available right now and a direct competitor to the Asus ROG Strix B550-E. The motherboard looks great thanks to RGB lighting zones on the motherboard itself and offers plenty of cooling. It has a beefy 14+2 Infineon VRM (70A), high-speed RAM OC support up to 5200 MHz, support, and no less than three PCIe Gen4 M.2 slots with heatsinks. Due to the chipset limitations, the Gen4-capable M.2 slots will share the existing PCIe bandwidth.

Gigabyte B550 Aorus Master

 

This ATX motherboard also offers reinforced DIMM slots and a single reinforced PCIe x16 slot for large, high-end GPUs. However, unlike Asus’ top model, the Aorus Master does not support SLI. The board also comes with a debug LED which will give you an error code if something goes wrong. This can be very helpful when troubleshooting. You also get 2.5 GbE and high-speed wireless connectivity out of the box. Needless to say, this is one of the most expensive B550 motherboards on the market. Instead, it has to compete with mid-range X570 offerings.

GIGABYTE B550 AORUS PRO & PRO AC

On the first step down the ladder from the Aorus Master is the B550 Aorus Pro, which is available with or without onboard wireless (AC) connectivity. This board shares several features with the top model, including 2.5 GbE, 5200 MHz RAM (OC) support, and a premium audio chip.

Gigabyte B550 Aorus Pro

Many of the high-end features also had to go and that most notably includes the triple M.2 slots. The VRM has been downgraded from a 16-phase 70A solution to a – still highly capable – 14-phase 50A alternative.

GIGABYTE B550 AORUS ELITE

Next, we have the B550 Aorus Elite. This board comes in at a more attractive price point, making it attractive to builders looking for a good mix of features and value. But although it’s a scaled-down version of the Pro, Gigabyte hasn’t made too many cutbacks on the Elite. What it mainly lacks compared to the slightly more expensive model is the onboard WiFi option, high-speed RAM OC support, and dual M.2 heatsinks.

B550 AORUS ELITE

 

The Elite’s 14-phase 50A VRM has been left intact from the Pro model, and the same is true for the 2.5 Gbps LAN. The motherboard comes with 3 PCIe 16x slots and the top one is reinforced for better graphics card support. On the whole, it’s a well-balanced mid-range motherboard for a mid-range chipset.

Reviews: No reviews available at this time.
GIGABYTE B550M AORUS PRO

Gigabyte’s B550M Aorus Pro is not just an mATX version of the ATX board with the same name. It’s a lower-end product overall, with no 2.5GbE, a less capable VRM, and no ultra-fast RAM support. However, this is also reflected in the pricing and the B550M Pro is no low-end board compared to some (actually most) of its mATX competitors.

GIGABYTE B550M AORUS PRO

As with the high-end Aorus boards, you get dual M.2 slots and USB 3.2 Gen2 connectivity (1 Type-A + 1 Type-C). And for an mATX motherboard, the 10+3 VRM solution with a large heatink on top should be more than enough for any 3rd-gen Ryzen CPU. Also like its ATX namesake, the GPU slot is reinforced to prevent any sizeable card from sagging. All in all, the B550M Pro looks like a very attractive mATX board from a value perspective.

Reviews: No reviews available at this time.
GIGABYTE B550M AORUS ELITE

Compared to the B550M Pro, the B550M Elite is a somewhat less interesting motherboard from a value standpoint. The price difference is relatively small versus the Pro, yet the 5+3-phase VRM is the same one found on Gigabyte’s budget boards, as is the audio chip and the 1 GbE Realtek LAN chip – and there are no USB 3.2 Gen2 ports.

Gigabyte B550M Aorus Elite

There’s not much that separates the B550M Elite from Gigabyte’s entry-level models other than the design, but it does have a reinforced GPU slot and two M.2 slots.

Reviews: No reviews available at this time.
GIGABYTE B550I AORUS PRO AX

This is a comparatively high-end ITX motherboard that comes with two reinforced DIMM slots and a single reinforced PCIe slot for your graphics card. Even though this is a smaller motherboard, you still get 2 M.2 slots. One is above the PCIe slot under the heatsink and the other is located at the back of the motherboard.

B550I AORUS PRO AX

The B550I has a 6+2-phase VRM and a single 8-pin power connector that provides power to the CPU. In addition, you get onboard Intel AX200 WiFi, 2.5 GbE LAN, and the same ALC1220-VB audio chip as in the high-end Master and Pro ATX boards. All things considered, this is a small premium motherboard that is a strong competitor to the Asus B550I if you want to build a small form factor PC without compromising on performance.

GIGABYTE B550 VISION D

One board from Gigabyte really stands out from the rest and that’s the B550 Vision D. This motherboard is aimed at content creators and supports ECC (error-correcting code) DRAM, which is useful in professional workstations. Regular non-ECC memory is however also supported. Another key feature of the Vision D is an Intel Titan Ridge Thunderbolt 3 controller that provides 40 Gbps of bandwidth via the board’s dual USB-C ports.

Gigabyte B550M Vision D

The Vision D also comes with the same 14-phase 50A VRM as the ATX models of the Aorus Pro and Elite. It also has reinforced RAM/PCIe x16 slots and includes heatsinks for both M.2 SSD slots. In other words, this is a premium B550 board with a premium price tag that will mainly appeal to those who need either ECC RAM and/or Thunderbolt 3 support.

GIGABYTE B550 GAMING X

Gigabyte Gaming-branded motherboards are usually value-oriented and the B550 Gaming X is no exception. It comes in below all of the Aorus models but remains a cut above the entry-level models by a fair margin, particularly in the VRM area. The ATX B550 Gaming X uses the same 10+3 VRM design as the mATX B550M Aorus Pro, which is likely more than sufficient for most builders though not quite on par with the full-size ATX Aorus boards.

Gigabyte B550 Gaming X

While the B550 Gaming X is reasonably priced and comes with a good VRM, you also have to contend with a few significant trade-offs compared to the more expensive models. There is no high-speed memory OC support, no 2.5 GbE, and no reinforced GPU slot. On the plus side, it does have dual M.2 slots as well as a single USB 3.2 Gen2 port (Type-A) on the back panel. All in all, these are acceptable compromises in this price range, so the B550 Gaming X will likely find its way into many entry-level and mid-range gaming builds.

GIGABYTE B550M GAMING

Much like the other micro-ATX B550 motherboards from Gigabyte, the B550M Gaming is not only a physically scaled-down version of the ATX model – it’s also equipped with less powerful components in key areas. Notably, the VRM design is shared with Gigabyte’s entry-level boards, there is only one M.2 slot and the motherboard lacks USB 3.2 Gen2 support. As is often the case with mATX motherboards, this board only has two instead of four DIMM slots.

Gigabyte B550M Gaming

What the B550M Gaming has that the B550 Gaming X doesn’t is a reinforced GPU slot.

GIGABYTE B550M DS3H, S2H & H

Gigabyte’s UD or Ultra Durable range consists of three different entry-level mATX motherboards, all of which use the same 5+3-phase VRM but differ in a few areas. The B550 DS3H is the most capable version, with four DIMM slots and dual M.2 slots, while the S2H and H versions have room for just one M.2 SSD and two RAM modules. Cooling components such as the VRM heatsink have also been scaled down.

Gigabyte B550M BS3H

A single 8-pin connector provides power to the CPU but that is fine as overclockers are not the intended audience for these motherboards.

MSI B550 GAMING CARBON WIFI

The B550 Gaming Carbon WiFi is MSI’s flagship B550 motherboard. It comes in at a lower price than both the Gigabyte Aorus Master and the Asus Strix B550-E but is nearly as full-featured. While it doesn’t support SLI like the ROG Strix model or triple M.2 slots like the Aorus, it does come with a powerful 12-phase 60A VRM, 2.5 Gbps LAN, and an onboard Intel AX200 WiFi chip.

B550 GAMING CARBON WIFI

Other highlights include support for memory speeds up to 5100 MHz, a high-end audio chip, and a fair amount of cooling (both M.2 slots are equipped with heatsinks). In all, the Carbon WiFi is a premium B550 motherboard that doesn’t lack any key features except for SLI support. Though builders looking to use a multi-GPU setup are more likely to opt for an X570 board. The fact that it’s priced a bit lower than other flagship products is also a big plus.

Reviews: TechteamGB (video).
MSI MPG B550 GAMING EDGE WiFi

This is also a comparatively high-end motherboard with lots of bells and whistles but a slightly less sophisticated VRM solution than the B550 Carbon. Like the Carbon, however, this model comes with integrated Wi-Fi out of the box and has 2 M.2 slots but only the top one has a heatsink. The motherboard has proper cooling for the chipset and the VRMs, unlike the cheaper models.

MSI B550 Gaming Edge WiFi

There are two PCIe x16 slots and the top one is reinforced for better GPU support. Other features include pump fan support, 2.5G networking, and fast USB 3.2 Gen2 ports. RAM OC support is likewise identical to the more expensive MPG board. Although the 10-phase, 60A VRM is not quite on par with the Carbon, the price sticker on the Edge is more attractive – and considering the otherwise very similar feature set, MSI is essentially competing with itself in the flagship B550 segment.

MSI MPG B550 Gaming Edge WiFi Gaming Motherboard (AMD AM4,...
MSI MAG B550 TOMAHAWK

Another ATX alternative from MSI is the MAG B550 Tomahawk, which is a continuation of a popular line of value-focused motherboards with relatively few compromises. It has a more low-key design in black and grey, but appears to use the same VRM solution as the more expensive Gaming Edge. Like the higher-end models, the top PCIe slot is reinforced and it also comes with heatsinks for both M.2 slots, which is a plus.

MSI MAG B550 Tomahawk

There is no WiFi version of the Tomahawk, but in addition to the 2.5 GbE controller, MSI has added an additional 1 Gbps controller. RAM support and USB Gen2 connectivity are identical to the aforementioned models. You also get pump fan support and MSI’s onboard Mystic Light RGB effects. All in all, the Tomahawk is a strong mid-range B550 motherboard with few significant trade-offs compared to the flagship models. However, it’s also priced very close to the WiFi-equipped Gaming Edge, so unless you need the extra LAN controller, that board may be a more attractive option.

Reviews: Vortez, Overclock3D.
MSI MPG B550I GAMING EDGE WiFi

This is an ITX motherboard and MSI have been a bit creative with the design. There are 2 M.2 slots on this motherboard but you cannot really see them. One is located under the chipset cooler and the other is at the backside of the motherboard. As this is an ITX motherboard you only get 2 DIMM slots and a single PCIe slot for your graphics card. It is however reinforced for better support.

MSI MPG B550I Gaming Edge WiFi

For an ITX motherboard, the 8-phase, 60A VRM (+2-phase SoC power) is quite powerful and there’s plenty of onboard cooling. For one thing, a chipset fan is an unusual sight on a B550 board and the oversized VRM heatsink is complemented with a MOSFET baseplate on the back.

Reviews: No reviews available at this time.
MSI B550M MORTAR & MORTAR WiFi

This is a Micro ATX motherboard that’s available with or without an onboard Intel AX200 WiFi chip. The B550M Mortar essentially a scaled-down version of the Tomahawk or Gaming Plus, with a less powerful VRM but an otherwise quite comprehensive feature set. Like its ATX counterparts, it comes with 4 DIMM slots and two PCIe slots, with the top one being reinforced. It also offers dual M.2 slots but only one has a heatsink.

MSI B550M Mortar WiFi

You also get a 2.5GbE Realtek LAN controller with either version of this motherboard as well as USB 3.2 Gen2 support. All things considered, it’s an attractive mid-range motherboard if you are not interested in building a  full tower PC or simply want to scale back on cost.

MSI B550M BAZOOKA

Although it looks similar to the Mortar, the B550M Bazooka has more in common with MSI’s entry-level Pro lineup. Power delivery is handled by a 4+2+1 system, including four CPU power phases + 2 SoC + 1 APU. It will still be sufficient for a budget gaming system with no overclocking involved, but it’s obviously a much less sophisticated solution compared to the more expensive B550 boards.

MSI B550 BAZOOKA

 

What this mATX board also lacks compared to the Mortar is that the Bazooka comes with a standard 1 GbE controller instead of 2.5 GbE. Also, it has no USB 3.2 Gen2 ports and just a single (though reinforced) PCIe x16 slot. On the plus side, it does offer four DIMM slots and dual PCIe M.2 slots.

Reviews: No reviews available at this time.
MSI B550-A PRO

The MSI B550-A Pro is a budget-friendly motherboard in the standard ATX form factor, so you get four DIMM slots, two M.2 slots (one of which has a heatsink), and an extra pair of SATA connectors for a total of six. It also includes a pair of USB 3.2 Gen2 ports but only a 1 GbE controller and no WiFi chip, though this is to be expected in this price range.

MSI B550-A Pro

There are two PCIe x16 slots on the B550-A Pro and the top one is reinforced for better GPU support. As it’s an entry-level motherboard, the design is low-key and there are no RGB lighting zones. Even though this board is not aimed at overclockers, the 10+2+1-phase VRM solution is fairly powerful and similar to (if not identical with) the one found on the slightly more expensive B550 Gaming Plus.

Reviews: No reviews available at this time.
MSI B550M PRO-VDH (WIFI) & PRO-DASH

The B550M Pro-VDH, Pro-VDH WiFi and Pro-DASH are three nearly identical mATX motherboards and the cheapest B550 alternatives from MSI. All use the same VRM solution as the previously mentioned B550M Bazooka, i.e. 4+2+1 phases. Similarly, all three come with a single, reinforced PCIe x16 slot and two M.2 slots, as well as support for up to 128GB of RAM using four DIMM slots.

MSI B550M-PRO VDH WiFi

No USB 3.2 Gen2 ports are included and the LAN controller is a standard 1 GbE. The only board of the trio that stands out is the WiFi version of the PRO-VDH, which is equipped with an Intel Dual Band Wireless-AC 3168 chip. Business users are the intended audience for these boards and so, for obvious reasons, there are no RGB features.

ASROCK B550 TAICHI

This is ASRock’s top-of-the-line B550 motherboard and currently the most expensive model on the market, with an MSRP on par with some high-end X570 motherboards. What mainly sets it apart from the more affordable options is its high-end 16-phase VRM.  8+8-pin power connectors provide juice to the CPU, so in combination with the right cooling solution, you should be well-equipped for overclocking any CPU up to the Ryzen 9 3950 XT.

ASRock B550 TAICHI

Nearly half of the motherboard is clad in armor, which is to say a heatsink that covers the chipset and both M.2 slots. All three of the PCIe x16 slots are reinforced for better graphics card support. As with the flagship boards from other manufacturers, ASRock also provides integrated Wi-Fi out of the box in the form of an Intel AX200 chip. BIOS and CMOS clear buttons are available on the back. Unlike the Asus flagship, the B550 Taichi does not support SLI.

ASROCK PHANTOM GAMING B550 PG VELOCITA

This is the second most expensive ATX B550 model from ASRock but still much more reasonably priced than the Taichi. Nevertheless, you get 2.5 GbE, three USB 3.2 Gen2 ports (one Type-C via header), dual M.2 sockets, and two reinforced PCIe x16 slots for graphics cards.

ASRock Phantom Gaming B550 PG VELOCITA

The VRM consists of a 14-phase solution and the board comes with 8+4 pin power connections for the CPU, so it should be ready for quite a bit of overclocking with the right cooling solution. Unlike the Taichi, the B550 PG Velocita is not entirely covered in armor but offers heatsinks over the SSD M.2 sockets as well as a couple of RGB lighting zones. Another M.2 slot can hold a Wi-Fi card if needed.

Reviews: FunkyKit.
ASROCK B550 EXTREME4

The B550 Extreme4 is also one of the higher-end B550 motherboards from ASRock. Other than the design, this board is in fact nearly identical to the PG Velocitá. ASRock appears to have used the same power delivery solution, including 8+4 pin connectors for the CPU. Likewise, there are two M.2 SSD slots along with one for a WiFi chip (the I/O panel has also been prepared with antenna connectors for this purpose. Both of the PCIe x16 slots are reinforced.

ASRock B550 EXTREME4

One of the few differences between the B550 Extreme4 and the PG Velocitá is that the Extreme4 has no extra front-panel header for a USB 3.2 Gen2 Type-C port. Considering the similarities and that the price is a fair bit lower than for the Velocitá, the Extreme4 looks like a considerably more attractive alternative in terms of value.

Reviews: goldfries (video).
ASROCK B550 STEEL LEGEND

The ASRock B550 Steel Legend is yet another ATX model that has most things in common with the PG Velocitá and the Extreme4 variations. It mainly differs from the Extreme4 in that it comes in black and white with some silver accents, and that it’s priced slightly lower. Power delivery (including the 8+4 CPU connectors) and RAM OC support is the same, as are the PCIe x16 and M.2 slot layout/functionality. Only the top PCIe slot is reinforced, however, but that hardly matters since the vast majority of builders will not run multi-GPU CrossFireX setups on this board.

ASRock B550 STEEL LEGEND

Another part that has been trimmed off versus the Extreme4 is the pair of onboard power/reset buttons. Other features such as heatsinks, USB 3.2 Gen2 ports, and WiFi antenna connectors are present on the Steel Legend as well.

Reviews: TechteamGB (video).
ASROCK B550 PRO4

Compared to the above ATX boards, the ASRock B550 PRO4 is a cheaper motherboard and in this case, it’s more obvious that some cost-cutting has been involved. While it does have all the basic features of the B550 chipset and then some, it uses a less capable 8-phase 50A VRM solution. However, this should still be more than sufficient for the 3rd-gen Ryzen chips and the board is actually fitted with 8+4 CPU connectors.

ASRock B550 PRO4

There are fewer RGB decorations, only a single M.2 heatsink (but triple slots, with one intended for WiFi, and no integrated I/O panel. One of the board’s two PCIe x16 slots is reinforced. All things considered, the ASRock B550 PRO4 offers a nice mix of features and value and will likely be a popular choice for mid-range gaming builds.

Reviews: No reviews available at this time.
ASROCK B550 PHANTOM GAMING 4 & 4/ac

On the next step down the ladder is the ASRock B550 Phantom Gaming 4 and 4/ac, which uses the same VRM as the Pro4 but cuts back on motherboard cooling parts and drops USB 3.2 Gen2 support. Only the chipset and VRM parts are fitted with small heatsinks and there are no RGB lighting zones like on the higher-end models. It still features dual M.2 SSD slots and you can get the board with integrated Wi-Fi out of the box (the two variations are otherwise identical).

ASRock B550 Phantom Gaming 4 ac

Interestingly, the motherboard still offers 8+4-pin connectors powering the CPU, so some overclocking should be possible in combination with the right cooling solution.

Reviews: No reviews available at this time.
ASROCK B550 PHANTOM GAMING-ITX/ax

This is another semi-premium ITX motherboard that competes with the Asus Strix B550-I, Gigabyte’s B550I Aorus Pro AX and MSI’sB550I Gaming
Edge WiFi. In other words, it’s intended for small form-factor PCs that does not compromise too much on performance. As with all ITX boards, you do have to compromise with the functionality to some extent, however. The B550 Phantom Gaming ITX/AX is limited to two DIMM slots and, of course, a single (reinforced) PCIe slot for your graphics card. It still offers some features that many ATX boards don’t, such as 2.5 GbE, three USB 3.2 Gen2 ports (one via header), and support for very high RAM OC speeds.

ASRock B550 Phantom Gaming ITX ax

Like all of the aforementioned competitors, this board also features dual M.2 slots thanks to some clever engineering. One is at the front while the other is at the back of the board. It also comes with integrated Intel AX200 WiFi out of the box. Additionally, the motherboard comes with a bit of RGB lighting and an integrated I/O shield for easy installation.

ASROCK B550M STEEL LEGEND

As the name implies, ASRock’s B550M Steel Legend is a smaller mATX version of the mid-range ATX board with the same name. It’s more affordable and some features had to go, but not that many – this is one of the more competent mATX B550 motherboards on the market. It even has a couple of RGB lighting zones. You get four DIMM slots and three M.2 slots (one of them intended for a WiFi card). One of the M.2 slots comes with a heatsink.

ASRock B550M STEEL LEGEND MATX

Other key features include 2.5 Gbps LAN and two USB 3.2 Gen2 ports. Last but not least, the board is equipped with a 10-phase VRM and 8+4 pin power connectors for the CPU which should allow for a bit of overclocking with a good CPU cooler.

Reviews: FunkyKit.
ASROCK B550M PRO4

This micro-ATX version of the Pro4 is an entry-level B550 motherboard but it’s not completely barebones. It has 4 DIMM slots and three M.2 sockets, one of which can be used to install an M.2 Wi-Fi card if you want to integrate wireless internet. There are two full-size PCIe slots and the top one is reinforced. The board also comes with some cooling in the form of a chipset, VRM, and single M.2 heatsink.

ASRock B550M PRO4

ASRock appears to have used the same 8-phase VRM solution as on the ATX version, but only a single 8-pin connector powers the CPU so the overclocking potential is going to be limited. USB 3.2 Gen2 support is also included. Due to the lower pricing and a feature set similar to the ATX model, this looks like an attractive part of a budget build.

ASROCK B550M-HDV

The B550M-HDV is ASRock’s cheapest board with the B550 chipset and possibly the cheapest of all B550 motherboards. In other words: if you want basic PCIe Gen4 functionality at the lowest cost possible, look no further than the B550M-HDV. This is a budget board in every respect, with an entry-level (4+2) VRM, two DIMM slots, no USB 3.2 Gen2, and just one M.2 slot.

ASRock B550M-HDV

ASRock has also skipped the cooling components, save for a tiny SoC heatsink. The board has a 1 Gbps Realtek LAN controller, ALC887 audio, and four USB 3.2 Gen1 ports on the back panel plus one in front via header. It also supports high-speed RAM up to 4733 MHz (OC). There aren’t many other features to speak of, but the board is priced accordingly and might still be an appropriate choice for an entry-level build where PCI Express 4.0 is required.

Reviews: No reviews available at this time.
ASROCK B550M-ITX/ac

For now, there is only one budget-oriented Mini-ITX B550 motherboard on the market and the ASRock B550M-ITX/ac is it. This motherboard will be yours for about $70 less than the upper mid-range ITX boards from ASRock, MSI, Asus, and Gigabyte. Of course, a number of compromises have to be made when opting for this more affordable ITX alternative. There is no high-speed LAN, USB 3.2 Gen2, or dual M.2 slots, but it does come with Intel 802.11ac WiFi out of the box.

ASRock B550M-ITX/ac

The B550M-ITX/ac is also equipped with an M.2 heatsink and it supports RAM speeds of up to 4600 MHz. Power delivery is handled by a 6+2-phase VRM, which should be more than adequate since anyone looking to overclock the most demanding Ryzen chips will likely look elsewhere. While it’s popular to build high-end systems in small form factors, not everyone wants to spend an arm and a leg on an ITX build, so it’s great that there is at least one B550 ITX option.
