What CPUs can you use with a 550W 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 ~150W 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 145W for the CPU.
With 145W you can squeeze in CPUs such as Intel Core i7-14700K, Intel Core i7-13700K, Intel Core i7-12700K, AMD Ryzen 7 5800X3D, AMD Ryzen 5 7600X.
