The AMD Ryzen Threadripper 3960X is a beastly processor, even though it's the entry open for the third-gen Threadripper family. It still has a rated TDP of 280W, which is considerable, and we'd recommend a PSU with an output of at least 750W. To make things easier for you to decide, we rounded up some of our favorites.

TRx40 motherboards, which are required for AMD Ryzen 3000-series processors, require two 4+4 CPU power connectors, so it's essential you choose a PSU with full support for this. Our collection of featured power supplies all work perfectly with TRx40 motherboards, as well as the Threadripper 3960X CPU.
If we were to recommend one PSU to go with, it would be the EVGA 750 GQ. It's not the fanciest PSU on our list, but it is the most affordable, making it an ideal choice for those who are building their first Threadripper-powered PC. With a capacity of 750W, it can handle the powerful CPU, as well as a dedicated GPU and other hardware.
If you want to go all out with a multi-GPU build, maxing out all RAM slots, adding many expansion cards and other accessories, you may want to look at the Corsair HX1200 with 1,200W of power and a 10-year warranty.
