Soldato
I'm running a 3090FE on a 750w PSU - A Seasonic prime Ultra Snow Titanium.
Yea, when I had my 3090FE it was running on my current PSU (Corsair SF 750W SFX) perfectly fine
Nice and small but worked fine for the 3090 and is perfectly fine with my 3080 even whilst mining with the CPU maxed out doing some encoding at the same time
