What make and model? If it's a good one it should be more than fine. The 7800X3D is pretty efficient. Rated at 125w but only actually draws about 88w under load.
I haven’t bought it yet, I was gonna get a BeQuiet one (ATX 3.0, PCIE 5.0 etc) but im open to suggestions.
Pretty much as title really although there’s a chance i may get a 7900XT instead.
Thanks
Thread gatecrasher here, 850w is ample power for a 7900X3D and 6800 XT right?
