Hopefully, by now you have a clear idea on the B450 motherboard you should get for yourself. Whether you are building a PC for overclocking and squeezing the most performance out of it, or you are looking for something budget-friendly and will provide a stable Ryzen PC build, the motherboard should be as important as the CPU or Graphics Card. In general, while looking for any motherboard, the VRMs and cooling are most important and apart from that, BIOS Flashback, Wi-Fi, Intel LAN are also nice features to have.

Just make sure the board is compatible with your processor and ask your retailer for the latest BIOS update if it needs one. The AMD B450 motherboard chipset is perfect for power users who want high performance and flexibility but don’t need the maximum PCIe bandwidth required by multi-GPU configurations.

So, that was our take on the 7 Best B450 motherboards for Ryzen 2nd and 3rd gen processors. We hope our guide has helped you narrow down your choices and learn more about motherboards. Many of these motherboards have very similar feature sets and that makes it a very confusing decision to pick one.

We have taken care to provide the best possible options in multiple categories. No matter what your preference is, you should find the one suited for you, and any of these would be a solid choice as long as you get the board at its regular retail price. If you have any other doubts or suggestions feel free to leave them in the comments section below.


Yes, all B450 motherboards support Ryzen 3000. However, do note that while some boards may come ready out of the box like the MSI Gaming Pro Carbon Max Wi-Fi, many others may require you to do a BIOS upgrade.

We recommend you get a motherboard with the BIOS flashback feature, which allows you to update the BIOS without a processor, memory, or video card. USB BIOS Flashback comes in handy if you are, for example, going to use 3rd gen Ryzen and the motherboard doesn’t have the updated BIOS to support the processor. Most MSI boards have the Flash BIOS Button, which makes them really the first choice for many users. Otherwise, make sure before buying if the board needs a BIOS update to work with your CPU.

Yes, B450 can handle Ryzen 9 3900X/3950X with stock speeds, just fine. A high-quality B450 board like the MSI Gaming Pro Carbon Max will be enough unless you plan to overclock it. The Ryzen 9 3950X installs in the AM4 socket which is what we have on the B450. The 3900X is an efficient CPU which is built on 7nm architecture. It doesn’t need tons of VRMs like the i9-9900K. So any decent B450 motherboard will suffice.

You might consider buying a B550 or X570 board if you can extend your budget because it will have much better VRM for overclocking and it will last longer, so you won’t have to replace the B450 board if you plan to upgrade your CPU in a couple of years. If your aim is to push it to its limits through overclocking and if you are spending this much on a CPU, why not spend more on a better motherboard as well.

The B450 and the X470 are AMD’s mid-range chipsets for people building a budget oriented PC and aiming at decent gaming or general use. The X470 is a higher end board than the B450 and thus has more features. Although they have the same CPU compatibility. Some of the additional features include SLI support, more USB ports, a couple more PCIe 2.0 and SATA3 slots. Some might even have slightly better VRMs.

The difference in performance is negligible though, and the X470 boards don’t offer any huge benefits over the B450 equivalents to justify the high pricing. For most people, B450 makes much more sense.

AMD has suggested that the 400 series chipsets will provide enough support for the latest Zen 3 processors, and you don’t have to worry about future-proofing if you get these. If you really want the latest and best chipsets, you may want to take a look at the X570 motherboards, but they cost a lot more.
