5 Best B450 Motherboards For Ryzen Processors in 2021

The B450 chipset is one of the most popular chipsets from AMD even in 2021 due to its exciting value proposition and excellent CPU compatibility. AMD has even decided to support the new Ryzen 5000 series (we have a separate motherboard guide for that) of CPUs based on the Zen 3 architecture on the B450 platform due to community demand. This means that B450 is the only platform on the AMD side that can support all four generations of Ryzen processors that have been released as of the time of writing. That is staggering in the modern PC gaming landscape where it is hard to find a chipset that gets more than two generations of CPU support. Our best b450 motherboard guide is all circled around this amazing chipset.

The extraordinary CPU compatibility is not the only thing that B450 excels at. Most of the motherboards of this chipset are quite affordable and, therefore, offer excellent value when compared to newer options such as B550 and X570. Not only that, but the B450 chipset also supports overclocking which means that you are not really losing a whole lot if you choose B450 over X570 in favor of some savings. One big drawback of B450, however, is the PCIe Gen 4 support which it lacks, but one can only have so many features at this price point. B450 motherboards still make a lot of sense in 2021 due to their low costs, high compatibility, and diverse feature set.

The B450 Tomahawk MAX is also decently equipped in the features department. The MAX moniker means that the BIOS ROM size is doubled as compared to the standard Tomahawk, which means that this board has official support for the Ryzen 5000 series in 2021. There is one M.2 slot on the board, however, we feel that MSI could have easily included a second M.2 slot as there is ample free space and the competitors have done it as well. The board also lacks WiFi and the USB ports are somewhat limited in number, which can be a downside for people looking for lots of connectivity options. Still, the excellent pricing of the board makes it an easier pill to swallow.

All in all, the MSI B450 Tomahawk MAX can be considered one of the very best B450 motherboards on the market right now, and arguably the best one for CPU overclocking specifically. It has an exceptional VRM design that is hard to find in this price bracket and is priced very competitively which makes it an excellent purchase, despite a few shortcomings in the features department.

The ASUS ROG Strix line is the premium lineup from ASUS when it comes to motherboards and their B450 offerings are no exceptions. The ROG Strix B450-E goes head to head with the MSI B450 Tomahawk MAX for the best overall B450 motherboard, which gives further fuel to the MSI vs. ASUS debate. While the MSI offering is a bit cheaper and a bit better when it comes to VRM design, the ASUS option is more well-rounded and a bit more packed with features.

While the B450 motherboards from the ASUS Strix line did have some well-documented problems with their VRM thermal solutions, the Strix B450-E is safe from those issues. Users have to be careful to go for the ASUS ROG Strix B450-E when shopping for the motherboard, and not with the ROG Strix B450-F since that board had terrible VRM performance. The B450-E, however, is one of the top performers in the B450 category and can easily handle overclocked Ryzen 5s and even some Ryzen 7 CPUs without breaking a sweat.

From a features perspective, the B450-E from ASUS is probably the most well-equipped board in our lineup. It has WiFi included which is already a huge plus in this category. It also has two M.2 slots which give it the upper hand over the MSI B450 Tomahawk MAX in this department. Aesthetically, the board stands out as well with the traditional aggressive styling that Strix boards are known for. The RGB is quite attractive as well, which is another plus point when it comes to aesthetics. Of course, the lighting can be controlled by ASUS Aura Sync software.

Overall, the ROG Strix B450-E might just be the best all-rounder B450 motherboard on the market. While the B450 Tomahawk is a little better in the power delivery department, the B450-E takes the upper hand when it comes to the overall feature set and aesthetics. However, the Strix B450-E is a little more expensive than the Tomahawk which is something to keep in mind.

When it comes to features, the B450 AORUS Pro delivers a middling experience, all things considered. It does have two M.2 slots with some nice heat-spreaders which are always a good addition to any board in 2021. However, it lacks WiFi which can be a bit of a letdown to some users but can be easily rectified with an inexpensive PCIe WiFi card. Aesthetically, the board stands out quite a bit with the use of brushed aluminum accents here and there, complemented by a decent helping of RGB lighting. The lighting is also strategically placed which gives the board a really nice and sophisticated look.

The Gigabyte B450 AORUS Pro delivers a solid power delivery system and combines it with a decent feature-set which makes it an attractive B450 option in 2021, however, it is also priced a bit higher than competitors in this category. The standout point of this board is certainly its aesthetics, which is a subjective matter, so that puts it at a bit of a disadvantage compared to the offerings from ASUS and MSI in our list. Still, the B450 AORUS Pro is an excellent option that could be perfect for just the right buyer.

4. Best Budget B450 Motherboard - ASUS TUF B450-Plus Gaming

Bang For The Buck

Pros

  • Decent Power Delivery
  • High RAM Compatibility
  • Quite Affordable
  • Official Support for Ryzen 5000 Series

  • Lack of WiFi
  • No RGB Lighting
  • Not The Best VRM Thermal Performance

619 Reviews

Form Factor: ATX | Memory: 4x DIMM, 128GB, DDR4-4400 | Expansion Slots: 2 x PCIe 3.0/2.0 x16, 3 x PCIe 2.0 x1 | Video Outputs: DVI-D and HDMI | USB Ports: 7x rear IO, 6x internal | Network: 1x 1 GbE LAN | Storage: 1x M.2, 6x SATA

ASUS has branded the TUF series to be its value-oriented lineup of motherboards, and the TUF B450-Plus continues that tradition. Not only is it one of the cheaper motherboards in our lineup, but it is also quite an excellent one considering its price point. It ditches some unnecessary bells and whistles which don’t contribute a whole lot to performance and instead lowers the price point to appeal to a wider audience.

When it comes to VRM design and power delivery, the TUF B450-Plus doesn’t particularly stand out among the pack, but it is still more than capable of handling most Ryzen 5 CPUs at overclocked settings. The thermal management of the VRMs is not the very best, but you shouldn’t have any problems with VRM temperatures unless you are creating artificial situations. Overclocking Ryzen 7 and Ryzen 9 parts should be avoided on this motherboard, however, running these CPUs at stock settings should be perfectly fine which is more than one can ask for at this price point.

The TUF Gaming B450-Plus is not the best B450 motherboard on our list when it comes to features, but that is to be expected due to the value that this board is targeting. It does not have WiFi and only hosts one M.2 slot, which are both considerable letdowns. As far as looks go, the board is quite simple and understated which can be a good thing or a bad thing depending on the buyer. There are no lighting zones on the board which might be a bummer for some buyers who might want to add a personalized touch to their build.

All in all, the ASUS TUF B450-Plus is a great value-oriented motherboard that offers a decent power delivery setup at a competitive price point and should be a good choice for those who are looking to maximize their bang for the buck. It might not have the latest features, but it is certainly not completely barren or outdated in this department either, which is good news for potential buyers.

5. Best Micro-ATX B450 Motherboard - MSI B450M Mortar MAX

Compact But Powerful

Pros

  • Very Solid Power Delivery
  • Two M.2 Slots
  • Ideal for Compact Ryzen Builds

Cons

  • No WiFi
  • Only 4 SATA Ports
  • Relatively Pricy for a Micro-ATX Board
  • Questionable RGB Placement

914 Reviews

Form Factor: Micro-ATX | Memory: 4x DIMM, 128GB, DDR4-3466 | Expansion Slots: 2 x PCIe 3.0/2.0 x16, 2 x PCIe 2.0 x1 | Video Outputs: DisplayPort and HDMI | USB Ports: 8x rear IO, 6x internal | Network: 1x 1 GbE LAN | Storage: 2x M.2, 4x SATA

The MSI B450M Mortar is one of those motherboards that seem too good to be true until you dive a little bit deeper into it. It is one of the most impressive B450 motherboards on the market, and certainly the best B450 motherboard in a micro-ATX form factor. Essentially, it is just a compressed B450 Tomahawk with some features added or removed to make a somewhat different product, which is definitely not a bad thing considering the pedigree of the Tomahawk.

Under the substantial VRM heatsinks, we do find a very solid power delivery system that is basically identical to the one found on the B450 Tomahawk. This is excellent news for fans of the micro-ATX form factor since they now have an option to buy a micro-ATX B450 motherboard with a robust VRM design. This power delivery system should be perfectly fine for all Ryzen 5s and even Ryzen 7 CPUs up to the Ryzen 7 3700X, which is a better result than most people would associate with a micro-ATX B450 board.

MSI B450M Mortar MAX – Image: MSI

In terms of features, the B450M Mortar MAX is adequately equipped considering the price tag of the board and its micro-ATX form factor. It does have 2 M.2 slots, which is even more than the B450 Tomahawk, despite the latter being a full ATX motherboard. However, the Mortar only has 4 SATA ports and lacks WiFi which are both features that would have been nice additions to this package. Furthermore, the Mortar is often found similarly priced or even more expensive than the B450 Tomahawk MAX on online retail sites, which is unfortunate for the micro-ATX offering in terms of value.

Based on these findings, it is clear that the B450M Mortar MAX from MSI is very similar to the B450 Tomahawk, albeit in a smaller form factor. It does have a similar feature set too but is a bit pricy for a micro-ATX board of its class. However, for anyone looking specifically for a B450 Micro-ATX motherboard to pair with your micro-ATX case, it does not get a whole lot better than this.

Frequently Asked Questions About B450 Motherboards

Is the B450 still good in 2021?

Yes, the B450 platform is still perfectly viable in 2021 and many enthusiasts believe it to be the best budget-oriented platform that one can buy right now. It is incredibly versatile as it can support almost all the generations of CPUs that AMD has released under the Ryzen brand (depending on the particular model), and also supports overclocking which can unlock even more performance from your CPU if you need it. The B450 boards are also incredibly affordable which makes them an excellent value in 2021, and they can make excellent pairings with mid-range CPUs such as Ryzen 5s.

Is X570 better than B550?

Generally, the X570 chipset is considered to be the premium option from AMD when it comes to motherboards, so it is better than the B550 option all things considered. The X570 chipset has more PCIe Gen 4 lanes, therefore it can support PCIe Gen 4 in both M.2 slots which is not the case with B550. Furthermore, the X570 motherboards have higher CPU and RAM compatibility than B550 and are built better for overclocking. However, in terms of value, the B550 is still the superior option.

Should I go with B450 or B550?

As of the time of writing, it is best to go for a B550 motherboard if you are building a new mid-range Ryzen build from scratch. The big advantage that B550 holds over B450 is the support for PCIe Gen 4 which is becoming more and more important in the PC gaming landscape going forward. The price difference between the B550 and B450 motherboards is not that much, so it makes perfect sense to go for a B550 motherboard in 2021 for a new build with a Ryzen 3000 or Ryzen 5000 CPU.

Are B450 motherboards overclockable?

Yes, the B450 chipset does officially support overclocking. While you may not be able to break overclocking records with these motherboards, it is certainly nice to have overclocking support so you can squeeze a bit more performance out of your system if you need to. Overclocking mid-range CPUs such as Ryzen 5s and Ryzen 7s should be possible and rewarding on B450 motherboards, however, we would advise against overclocking any Ryzen 9 parts on this chipset as generally the VRMs on these budget motherboards are not robust enough to handle those scenarios.

Does Ryzen 5000 support B450?

Yes, the Ryzen 5000 series of CPUs based on the Zen 3 architecture are officially supported on the B450 and X470 chipsets as well. AMD first announced that they would not support the new Ryzen 5000 CPUs on 400-series chipsets, but due to community backlash they quickly changed their stance and allowed the motherboard manufacturers to support the new CPUs in their boards should they see fit. As a result, the new Ryzen 5000 series CPUs are supported officially on the majority of B450 motherboards.

Factors to Consider While Buying

While shopping for a motherboard in the modern landscape, it is impossible for any novice or even expert PC builder to not get confused by the marketing jargon and meaningless target phrases that are rampant on the product pages of motherboards. The motherboard is a very critical, yet often undervalued component of gaming PCs, and it is very easy to spend way more or way less on a motherboard than you actually should. So, how much should you actually spend on a motherboard? Well, it depends on several factors which should be considered in the purchasing process, some of which are listed below.

VRM Design

For motherboards that support overclocking, such as the B450 motherboards, it is very important to research about the VRM quality of the board that you want to buy. A motherboard’s VRM or power delivery system is tasked with taking the direct power that is coming from the wall and converting it into clean, stable, and usable power for the CPU itself. The VRM design and its thermal management are absolutely crucial in order to get the best overclocking performance from CPUs, and they should definitely be considered in the purchasing process. The size and design of the VRM heatsinks also play an important part in the overall performance of the VRM.

Upgrade Path

Even before you start looking for motherboards on the market, you have to decide what chipset or platform you need to purchase in order to get the best upgrade path down the line. For instance, in the case of Ryzen, AMD has made it very easy for the consumers to upgrade to the next generation without changing the motherboard since they support multiple generations on a single chipset. A B450 motherboard purchased with a Ryzen 2000 series CPU can also be used with your brand new Ryzen 5000 series processor should you choose to upgrade, and that is great when you want to maximize the value proposition. The upgrade path should be mapped out beforehand, and one should choose only the platform that suits your particular preferences in this regard.

While these are some of the more critical factors to consider when making a purchase decision about a motherboard, there are certainly many more that also should be in the back of your mind when buying a motherboard. To get an in-depth look at all the factors that you should consider in this process, you can visit our detailed motherboard buying guide, which will help you through the purchasing decision by discussing each and every factor in a comprehensive manner.
