CPUs you can use with a 750W PSU

Assuming you already have a ~200W GPU, here's a compiled list of possible CPUs you can use:

CPU TDP Quick Buy
AMD Ryzen 9 7900X 170W
Intel Core i7-14700K 125W
Intel Core i9-14900K 125W
Intel Core i5-13600K 125W
Intel Core i7-13700K 125W
AMD Ryzen 7 5800X3D 105W
AMD Ryzen 5 7600X 105W
AMD Ryzen 7 7700X 105W
AMD Ryzen 5 7500F 65W
AMD Ryzen 5 5500 65W

What CPUs can you use with a 750W 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 ~200W 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 275W for the CPU.

With 275W you can squeeze in CPUs such as AMD Ryzen 9 7900X, Intel Core i7-14700K, Intel Core i9-14900K, Intel Core i5-13600K, Intel Core i7-13700K.
