Best B450 Budget Motherboards For Old Gen AMD Processors

The B450 chipset is one of the most popular chipsets from AMD even in 2022 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 2022 due to their low costs, high compatibility, and diverse feature set.

Frequently Asked Questions About B450 Motherboards

Is the B450 still good in 2022?

Yes, the B450 platform is still perfectly viable in 2022 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 2022, 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 2022 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.
