When it comes to looking at power supplies you want to know how much power you need. With one of the specifications of PSUs is how much power they can provide.
So to know how big of a power supply you need, you have to add up your components. So we first look at the TDPs of the new CPUs.
There we see 170W for the top two choices, Ryzen 9 7950X and 7900X. Whilst the lower two options, the Ryzen 7 7700X and Ryzen 5 7600X, have a rating of 105W.
Although in terms of AMDs spec these tend to be the thermal design and not direct power consumption so it is likely higher than that.
