There is absolutely no way to deny that both the Ryzen 9 3950x and the Ryzen 9 3900X are among the most popular and most powerful processors available in the market.
However, you also have to keep in mind that these CPUs are generally paired with higher end components that have a higher power draw, and naturally, they require a good power supply, as well.
That being said, if you are looking to get your hands on a system based on either of these processors, you will need a good power supply to boot. Below, you can see the best PSU for both Ryzen 9 3950x and 3900x.

After all, you will not pair your high end gaming PC with a cheap power supply. The Corsair RM850x is definitely one of the best PSUs available in the market.One of the best thing about this power supply is the fact that has a zero RPM fan mode, which means that the fan won’t be spinning until there is high load on the power supply.
Speaking of high load, another great thing here is that the power supply is capable of delivering high power even on higher temperatures, and you are also getting fully modular power supply cables, which are only going to make your overall experience much better.
The power supply runs really cool, too, and the build quality is top of the line. Additionally, the PSU also ships with the legendary Corsair warranty, making things a lot more convenient for those who are looking to make things easier.
On the flipside, the only issue that I can think with this power supply is that it comes with cables that have capacitors and they make the cables slightly bulky.
Overall, the Corsair RM850x is definitely one of the finest power supplies available in the market, and if you are looking to build a high-end system, this is definitely the power supply that you should be going for and I can assure you that your experience won’t be ruined.
