Best B450 Motherboard for Ryzen 3000 | High Performance in a Budget


When you are building a PC, CPU’s choice is the key factor in deciding what other parts you’ll be using. The Ryzen CPU is currently the hype. So if you want to build a Ryzen PC, be it Ryzen 5, Ryzen 7, or even the latest Ryzen 9 3950X, you need a motherboard with the AMD socket. Now the most popular chipsets for this are the X470, X570, and the B450. Here we will compare all these chipsets for the latest Ryzen Zen 2 CPU. And review some of the best B450 motherboard for a Ryzen Zen 2 Build.

Get the best B450 motherboard for performance in a budget!

Now let’s get to the B450 motherboard. The B450 chipset offers some great budget options. Money saved here can be used in getting better RAM and GPUs for your build. Also, you get better VRMs then the previous generations like the X470 and B350. The baseline is if you are working on a budget and want good performance, then get yourself a B450 mobo.

Do you have the Ryzen 5 3600 or the Ryzen 5 2600 CPU? Please check out these tailored guides for choosing the best mobo for these Ryzen CPUs. Click here for review of best Motherboard for Ryzen 5 3600 and here for the best motherboard for Ryzen 5 2600. (PS: Budget category included!)

X470 X570 and B450 Comparison

If you take the older versions such as the X470 or B350, you’d need a BIOS update to support the Ryzen 3000 series. But that’s the only thing you’d need to run a Ryzen 3000 processor. Now with an X570 or B450 motherboard, you can directly run the Ryzen 3000 series processor.

Why should you get the X570 Chipset?

The X570 is the best among all these in terms of power and performance. You get Better VRMs with better cooling and high clock speeds. Also, this is the only chipset that supports PCIe 4.0. Plus, you get faster RAM support and even double RAM capacity. It also implements a thing called the precision boost overdrive, which tells the VRM how much space is there for overclocking. The X570 provides great headroom for the CPU to deliver more power to it. You can check out this article if you want to check out my X570 motherboard recommendations.

Why shouldn’t you get the X570? (Expensive)

But it may be the best choice for everyone to get an X570 motherboard. There are several reasons for that. Firstly, it’s expensive! Not everyone needs those premium features that they probably won’t even be fully using. Second, the PCI E 4.0 is the new-gen, and not many GPUs cannot properly utilize a PCI E 4.0. Also, you may not need a Faster VRM. The Ryzen 3000 CPUs are in the very power efficient, so you won’t need an X570 VRM when you can work with a cheaper B450 VRM.

Now let’s check out my recommendations for some good B450 motherboards.
