CPUs you can use with a 850W PSU

Assuming you already have a ~250W GPU, here's a compiled list of possible CPUs you can use:

CPU TDP Quick Buy
Intel Xeon 6747P 330W
Intel Xeon 6760P 330W
Intel Xeon 6768P 330W
Intel Xeon 6741P 300W
Intel Xeon 6745P 300W
Intel Xeon 6748P 300W
Intel Xeon 6737P 270W
Intel Xeon 6738P 270W
Intel Xeon 6740P 270W
Intel Xeon 6736P 205W

What CPUs can you use with a 850W power supply?

First of all we have to make an assumption regarding the rest of your PC, let's start by assuming you have a ~250W GPU. Also, we can assume that the rest of your PC components (MB, RAM, Fans, Storage, etc...) consume an additional 100W, and we'll have an additional 100W of margin. That leaves us with 315W for the CPU.

With 315W you can squeeze in CPUs such as Intel Xeon 6747P, Intel Xeon 6760P, Intel Xeon 6768P, Intel Xeon 6741P, Intel Xeon 6745P.
