Best B550 Motherboard

A Roundup of some of the Best B550 Motherboard for AMD Ryzen 5000 processors.

A motherboard plays a big role as other components like RAM, processor, storage, and graphics card. Now, what is a motherboard? In short, it is an electronic board that connects all the components. 

So, the specifications of a motherboard can highly affect the system’s performance, which is why we’ve made this guide.

The B550 chipset is the latest mid-range chipset for AMD Ryzen processors. Even though it is the latest chipset for the AMD Ryzen platform, it does not provide the DDR5 memory that you would find in Z690 chipset motherboards. 

The B550 motherboards are usually cheaper than X570 motherboards, but some of the best gaming motherboards are based on the B550 chipset.

Unlike the difference between the Z690 and B660 chipsets, the B550 and X570 chipsets are similar except for a few features.

The Pros:

  • Affordable price.
  • Solid performance.
  • Premium Audio and Networking.

The Cons:

  • Still expensive.

You may see similar models in Asus B550 and X570 motherboard lineup and similar features with a few things changed, including the chipset. The ROG Strix B550-E is not different from the X570 variant except for a few features, and both of the motherboards target the upper mid-range market.

This motherboard is packed with some of the impressive features rare under any other board within this price bracket. However, the B550 chipset makes it more affordable to the budget gamers, and they can consider it for mainstream processors like Ryzen 5 5600X, etc.

This motherboard offers a fine balance between the price and features, and the dark theme with some lightning makes it more appealing to users. The only things that are not black on this motherboard are the branding and slogans on the chipset and voltage regulator’s heatsink.

Overclocking the mainstream or flagship processor for this motherboard is not a problem at all because of the 14-phase voltage regulators. They are configured in a 12+2 phase configuration with extended heat spreaders to make them cool and don’t cause problems in overclocking.

There are many USB3 Gen2 ports on this motherboard, including Type-A and Type-C (10 Gbps) ports and some USB3 Gen1 (5 Gbps) ports. Spending a few more bucks can get you the Wi-Fi variant of this motherboard which comes with Wi-Fi 6 AX200 and 2.5G NIC with LAN Guard.

The ROG SupremeFX Audio CODEC S1220A is a premium controller that gives excellent sound quality to users and increases the overall price of this motherboard. Also, Asus Rog Strix B550-F is not affordable for all users, so if there is a price cut, it will be amazing or try to get it on some deal.

There are three M.2 slots on this motherboard with dedicated heat spreaders and six SATA 6 Gbps ports for storage. Three PCIe x16 slots are compatible with AMD Crossfire but don’t support Nvidia SLI because that’s only available on X570 motherboards.

There are many B550 motherboards that AMD has launched since the release of this chipset, and Rog Strix B550-E Gaming is one of the great options for budget overclockers. If you go with the cheapest option, you can get an Asus B550 motherboard for $140, while the most expensive one costs $280.


The B450 Tomahawk was known for its pricing and features balance, and B550 Tomahawk is not much different from it. These motherboard series used to be more budget-friendly, but now the company is moving towards premium features so that instead of saving some bucks, you can have a better product.

The compelling features in MSI MAG B550 Tomahawk are the 13-phase power design voltage regulators, configured in 10+2+1 phases and 60A MOSFETs. And the second thing that impressed me about this motherboard is the dual Ethernet ports, where one is controlled by 2.5G NIC while the other with 1GbE.

If you look at the MSI B550 product stack, there are a couple of motherboards covering every budget, ranging from 125 to 220 bucks. The previous generation Tomahawk motherboard comes with oversized VRM heatsinks, and this motherboard is quite the same but has an integrated IO cover.

We’ve tested this motherboard in different aspects, and in all our reviews and tests, this motherboard performs quite similar to the other mid-range B550 motherboard and has no improvements. With default BIOS settings, this motherboard managed to push our Ryzen 9 3900X to 4.6 GHz, which is not bad.

The top half section on this motherboard has a black body with grey contrast on the heatsink, making it appealing and similar to the X570 Tomahawk. Underneath these heatsinks, there are voltage regulators, which we’ve mentioned above, and they are capable of handling out Ryzen 9 3900X very well.

Moving to the bottom section of this motherboard, there is a chipset heatsink with RGB lights underneath and Tomahawk branding on it. There are two PCIe x16 slots and two M.2 slots with a dedicated heat spreader for them, and primary slots run at PCIe Gen4 mode while secondary slots are at PCIe Gen3 mode.

There are two USB 3.2 Gen2 Type-A and Type-C, two USB 3.2 Gen1 Type-A and USB 2.0 ports, and some other connectivity ports. I would not say this motherboard is too exceptional in connectivity options, but it just comes with features that a user needs in his build.

There is also a BIOS flashback button that can return the BIOS to its defaults without a CPU and most of the B550 motherboards we’ve reviewed lacks it. Overall this motherboard is a great option for this price, and you can pair it with any mid-range AMD Ryzen processor because of its affordable price.


The Pros:

  • Great performance.
  • 16 phases VRM.
  • Premium Networking.

The Cons:

  • Expensive price.

When you look at the Gigabyte B550 motherboards stack, there are around seven different options that you can choose from. This includes entry-level options like B550M DS3H or premium models like B550 Aorus Master, and you can choose what you need to save some bucks for other components.

The motherboard we’ve reviewed is the B550 Aorus Master, an ATX form factor board for high-end users. The price of this motherboard is slightly high as it costs similar to the X570 motherboards, but the premium features on it justify its price.

There are 16-phase design voltage regulators on this motherboard that comes in 14+2-phase configuration and 70A MOSFETs for Vcore. The looks of both of these motherboards are much similar, and it’s pretty hard to differentiate between them based on their looks.

The bottom section of this motherboard has three M.2 slots with dedicated heat spreaders for all of them colored in black and suits the dark color theme. For further storage expansion, there are six SATA 6 Gbps slots on this board that are right-angled and avoid clearance issues with large graphics cards.

The connectivity options on this motherboard are pretty interesting as it comes with USB 3.2 Gen2 Type-C (10 Gbps), USB 3.2 Gen2 Type-A (10 Gbps), and USB 2.0 ports. There are lot more ports on the rear IO, including display output ports like HDMI and DP, BIOS flashback button, etc.

The Q-Flash Plus is an amazing thing on this motherboard that can get you the corrupted BIOS back, and you don’t have to send the motherboard to the company. The controllers on this motherboard are expensive, Realtek 8125B 2.5 GbE LAN for networking and Realtek ALC1220-VB codec for premium audio.

This motherboard has four fan headers, two ARGB LED headers, two RGB headers, and one cooler header. There are three PCIe x16 slots on this motherboard, and for multiple graphics card configurations, it comes compatible with AMD Crossfire in 3-way.

You can install 128 GB of RAM on this board across four slots, and it supports excellent overclocking as you can take the memory clocks to 4800 Mhz. This is the best B550 motherboard, and you can consider it for high-end processors like Ryzen 9 5900X etc.

Gigabyte Aorus B550 Master is undoubtedly an excellent motherboard because of the premium features, but its pricing makes the users think about budget X570 motherboards. However, if you can get it on Cyber Monday or Black Friday, it will be excellent for you.


Although ASRock has some high-end motherboards in their Taichi or Phantom series, if you are looking for something more budget-friendly from them, I would recommend you get the ASRock Steel Legend B550 which is a successor to B450 Steel Legend we’ve reviewed before.

I usually prefer these motherboards for white gaming builds, or if someone has a meager budget and is looking for something that performs well, I recommend these options. This motherboard is affordable but doesn’t have all entry-level stuff packed on it, which makes it compelling.

There are 14-phase power design regulators on this motherboard configured in 12+2-phase configuration and 60A MOSFETs for Vcore. An extended heat spreader over the VRM ensures the low temperature of the voltage regulators and better overclocking options for mainstream Ryzen processors.

There are grey heat spreaders on this board, which contrasts with the black base, and some RGB lights over the IO cover and chipset heat spreader make it more appealing. ASRock motherboards are made up of high-density fiber, which ensures the long lifespan of the board and prevents them from humidity.

There is an ARGB and an RGB header with USB 3.1 Gen2 Type-C, which gives a 5 Gbps data transfer rate on it. While at the same time, the rear side of this motherboard has a USB 3.2 Gen2 Type-A and Type-C port, which offers a 10 Gbps data transfer rate and some other USB ports.

There are four memory slots on this motherboard, allowing you to install RAM up to 128 GB with overclocking up to 4733 MHz. With two M.2 slots with dedicated heat spreaders on them, you are also getting an M.2 Key E slot for a Wi-Fi card as this board lacks the integrated WI-Fi but features 2.5G ethernet.

The top M.2 slot and PCIe x16 slot runs at PCIe Gen4 Mode, while the bottom M.2 slot and PCIe x16 slot runs at PCIe 3.0 mode as B550 motherboards only offer 20 PCIe 4.0 lanes. There are six SATA3 6Gbps right-angled slots on this motherboard for further storage expansion.

This motherboard is an excellent consideration over lots of other budget or entry-level B550 motherboards because of its features and performance. While if you compare it with options like Gigabyte B550 DS3H, it has a lot to offer for almost the same price, making it compelling to users.


When there’s budget mentioned, there’s always MSI and they certainly proved it with their B550-A PRO providing not only premium features in the budget category but also keeping the cost low. It features 10-phase VRM, which are very good for this budget price along with beefy heatsinks to cool down those VRMs.

On the I/O ports side, it has two USB 3.2 Gen 2 ports, including Type-A and Type-C, with two USB 3.2 Gen 1 Type-A and four USB 2.0 ports along with an HDMI 2.1 port and a DisplayPort.

The price of ASRock B550 Taichi is around three hundred bucks, and this is one of the most expensive motherboards with this chipset I’ve reviewed so far. Taichi means a philosophical state of infinite potential, and this motherboard targets the high-end market on a budget chipset with premium features.

What you need to think about this motherboard is whether its price falls in the X570 pricing and is it worth buying in 2022, or should we look for some good X570 motherboard. ASRock B550 motherboards stack contains at least twelve boards ranging from $79 to $299, while my favorite Extreme 4 costs $180.

The 16-phase power regulators on this motherboard are something more than what other boards are offering, but 50A MOSFETs don’t. The voltage regulators are configured in 14+2 phases with extended heatsinks to maximize the overclocking potential without any problem.

We’ve put the same Ryzen 9 3900X on this motherboard to test its performance, and it pushed the clocks of this processor to 4.3 GHz (Two Cores/All Boosted). At the same time, the memory rating was DDR4 3600 MHz; it’s not bad but similar to most of the other B550 motherboards we’ve reviewed before.

The top half section of this motherboard contains the voltage regulators, the heatsinks are connected via heat pipe, and the shroud is made of plastic. Though it doesn’t make direct contact with the metal part, the old grey looks shifted to light brown and the metal shroud to plastic.

There are at least seven headers next to the VRM section, including some headers for fans, PWM fans, RGB lights, and ARGB lights. This board has four memory slots that accept DDR4 128 GB RAM, and this motherboard offers great memory overclocking compared to its competitors.

The bottom half section of this motherboard is covered with heatsinks, while on the left side, there is an audio section Realtek ALC1220 codec hidden under a shroud. Next to them, there are three full-length PCIe x16 slots for a graphics card with PCI Steel Armor, and the top one runs in PCI 4.0 mode.

There are two M.2 slots on this motherboard with dedicated heat spreaders on them where the top slot is “Hyper” supporting PCIe Gen4 mode while the bottom slot runs at PCIe Gen3 mode. Overall this motherboard is a great option for looking for something extra in the B550 category.


There aren’t many options available in the market about mini ITX motherboards, so going for a known brand like Asus is never wrong; the STRIX B550-I gaming proves itself by giving good VRMs, dual M.2 slots, and wifi6. Strix B550-I comes with 10-phases VRM, which are even enough to run 3900X.

For display ports, it features both HDMI 2.1 and a DisplayPort 1.4 as well as Audio CODEC S1220A for SupremeFX 7.1 Surround Sound supporting up to 32-Bit/192kHz playback.

Quick Buying Tips!

When buying a gaming motherboard, there are many things you need to take care of. Asus, Gigabyte, and MSI have launched many motherboards in their B550 product stack. And there is no reason to launch a similar motherboard, again and again, right? These motherboards come in different sizes, pack different ports and slots, and many other features, which we will discuss below. 

Chipset: Unlike the competition, we’ve many options when picking a motherboard for Ryzen processor. The company promised to bring support with older motherboards to support the latest Ryzen processors and fulfilled the promise. There are currently B450, B550, X470, and X570 motherboards that support AMD Ryzen processors, and we expect the X670 motherboards to launch soon. The functions of a chipset are explained there, but in short, it ensures the logical compatibility of the processor with the motherboard.

Overclocking: The overclocking performance of a motherboard depends upon its VRM section; as B550 is a budget chipset, its VRM section isn’t much powerful. That doesn’t mean this motherboard can’t overclock, but it may not be able to perform like X570 motherboards in overclocking. Though with budget processors like Ryzen 3 3300X, you will have excellent overclocking headroom. Also, if you are looking for a budget Ryzen 5 4600G motherboard, go for it.

Conclusion

There are a lot of B550 motherboards in the market, but it is up to you to decide what your needs are your preference and your liking. The given motherboards are there for you to choose from in case you need guidance while choosing. It all comes down to you whether you want certain features or not, features like overclocking, premium audio, wifi, multiple PCIe slots, or even USB ports.

Frequently Asked Questions

What is the difference between mATX and mini ITX?

Micro ATX motherboards are shorter than ATX but have essentially all the components of an ATX while on the other hand, mini ITX motherboards are small for compact builds and usually have only one PCIe lane.

Is good-quality VRM necessary?

Yes, it is, a lot; even if you don’t want to do overclocking, it’s always good to go for a decent VRM motherboard that can handle heat efficiently and won’t damage the components.
