Does that mean i have to feed 500w just for the GPU, or does that mean i just need a PSU that has minimum of 500w? i asked different people and i got different answers... someone told me that GPU is going to take 500w, and CPU,Fans,Hard drive will take about 300~400w, so i need like 700~800w PSU other guy told me that i just need a minimum of 500w PSU.. which one is correct? I have Antec 550w and it's "80 Plus Certified" does that mean i output only 80% of the 550w? will my PSU be okay with the HD 7850? i have: i5-2320 8GB Ram More about : question gpu power supply memadmax a b U Graphics card a b ) Power supply October 22, 2012 9:14:11 PM The "other guy" is correct, you want a 500 watt supply. m 0 l Ironslice a b U Graphics card October 22, 2012 9:53:57 PM You will be fine with that power supply. m 0 l Can't find your answer ?
