What is the most power hungry single-GPU (not dual-GPUs) ever from AMD/ATI and from NVIDIA?
I hope AMD is referring to a CFX system needing that many watts - I am using a 600w power supply with a Vega 64 LC edition. The most I've seen it at the wall was slightly less than 500w with a +15% powertune setting in the drivers.
That is the recommended power supply for Vega, granted you don't need that much, but for those crappy power supply makers out there, kinda need 1000 watts. AMD recommended 1000 watts at launch, but you don't need a 1000 watt if its a good power supply, 750 is probably enough.
Ah ok, couple of reviews that I read they just mentioned the 1000 watts, so assumed.... and yeah assumption is the Mother of all F' ups lol.
600w power supply is not at the wall watts, basically take rating divided by efficiency 600w/.9 = 667w. 500w/667w = .75 of rating. So getting close to 80%. With balance mode it runs around 430w -> 65% capacity of the power supply, Powersaver 390w -> 58%. Power supply is Corsair SF600 reviewed here:That means you are running close to 80% rated spec. (Depending on how good your power supply is and it's efficiency) You're really at the edge of the acceptable limit. I would think you will shorten your life of your PSU if you keep that up. Remember PSU's sustained output degrades over time. I would at least put a good quality 750W (Seasonic) in there. But then again, I never scrimped on what I consider backbone components...power supplies (seasonic)/motherboards (ASUS TUF)/Fans&Coolers (Never stock)
