If a GPU says it requires a 450W PSU... does that mean it draws that much? I would imagine not... If not how would I find out how much power it would draw?
I just bought this
bad boy and I have a 550W power supply... I don't want to blow anything since I have a lot of other crap pulling power too... Mainly my CPU which pulls 115W.
I plan on running my new GPU on it's own PSU rail if that makes a difference. What is the difference in the PSU requirement and what it draws?
