CPU for MSI B550-A PRO

Do you own a PC with MSI B550-A PRO motherboard and want to upgrade it with the best CPU this motherboard can support? Or do you just have this motherboard lying around and want to know what CPU to pair with it?

This post will help you get the maximum performance out of your motherboard so you won’t face any bottlenecks while gaming or performing any other intensive tasks.

When deciding to buy a new piece of hardware, budget is always a concern, so we’ve made sure to recommend CPUs that are both powerful and affordable. That’s why we did not only check which CPU is the most powerful one this motherboard supports. But we picked the three best CPUs for MSI B550-A PRO, each from one of the Ryzen 5, Ryzen 7, and Ryzen 9 series.

MSI B550-A PRO

This motherboard is based on an AMD B550 chipset and has an AM4 socket that supports AMD Ryzen processors. Intel is not an option here, of course.

There are multiple series of Ryzen CPUs: Ryzen 3, 5, 7, and 9. However, we don’t recommend any Ryzen 3 processors for this motherboard as they are not powerful enough, and you may face bottlenecks.

Important: To support the CPUs listed here, your MSI B550-A PRO must have BIOS updated to at least version V10.4.

MSI constantly adds support for new CPUs to their motherboard via BIOS updates. It’s recommended to update BIOS to the latest version.

You may also want to clear CMOS and reset BIOS to factory defaults before installing a new CPU.

AMD Ryzen™ 5 5600X

Supported since BIOS version V10.4

The AMD Ryzen 5 5600X is the perfect choice for your MSI B550-A PRO motherboard if you want to stay within the most affordable Ryzen 5 series. It has 6 cores and 12 threads, and its base clock is 3.7 GHz which can boost up to 4.6 GHz. It’s a high mid-range CPU that will offer you smooth gaming and good overall performance.

The AMD Ryzen 5 5600X has a TDP of 65 W and comes with a Wraith Prism cooler, which is a decent air cooler. However, if you want to push the CPU to its limits, we recommend getting a better aftermarket cooler.

AMD Ryzen™ 7 5800X

Supported since BIOS version V10.4

The best CPU that you can pair with the MSI B550-A PRO motherboard if you are looking for a powerful yet affordable option. The AMD Ryzen 7 5800X is an 8-core/16-thread processor with a base clock of 3.8 GHz and a boost clock of up to 4.7 GHz. This processor is considered the best bang for the buck.

AMD Ryzen™ 9 5950X

Supported since BIOS version V10.4

According to benchmarks, the best CPU for MSI B550-A PRO motherboard is AMD Ryzen 9 5950X. It is absolutely the most powerful CPU this motherboard supports. It is a 16-core, 32-thread processor with a base clock of 3.4 GHz and a boost clock of 4.9 GHz. One of the best processors on the consumer market offers outstanding performance and can handle any task you throw at it, whether it is gaming, video editing, or 3D rendering.

It has a total cache of 72 MB and a TDP of 105W. Cooler is not included, and it is recommended to use liquid cooling, especially if you plan to overclock.

How can we determine what are the best CPUs to pair with the MSI B550-A PRO motherboard?

1. First, we go to the official MSI website. Under the specification page for the MSI B550-A PRO motherboard, we find the section that lists all the supported CPUs.

2. We go to cpubenchmark.net from PassMark Software. They have great benchmarking tools and a database of over 1 million CPU performance tests. Checking the CPU Marks and price/performance ratio, we handpick the three best CPUs, each from Ryzen 5, 7, and 9 series. In this case, these are Ryzen 5 5600X, Ryzen 7 5800X, and Ryzen 9 5950X.

Recommended Coolers

Even though your existing CPU cooler should work just fine, we recommend getting a stronger cooler to keep your CPU temps in check, especially if you are about to overclock or perform tasks on your PC that push your CPU to its limits.

If your CPU of choice is AMD Ryzen 5 5600X, you may want to keep the stock Wraith Prism cooler that comes with it. It is a decent cooler if you are not planning to overclock.

For AMD Ryzen 7 5800X, and Ryzen 9 5950X, we recommend the following:

Noctua NH-D15 chromax.black

The Noctua NH-D15 is widely known as the premium-quality quiet air cooler available today. Due to two large 140mm fans, it’s exceptionally quiet. You can hear it only when the CPU is pushed to the limits.

It’s pretty big, though. So make sure it should fit your PC case. (You can check the dimensions here.).

If this is a problem, you may check Noctua NH-U12A , a smaller version with 120mm fans. Also a premium cooler with excellent cooling performance.
