I am looking to buy a EVGA GTX 560ti, but the EVGA site recommends a PSU that can do 30 amps on the +12v rail. I have an Antec Earthwatts 650watt psu, that has multiple 12v rails but the max one can go is 25 amps.
Will it work on my psu if I use 2 different 12v rails, which would in theory give it almost 50 amps to use? or does it need to be able to hit 30amps on 1 rail?
Also does anyone know the amp requirements for the AMD 6950's? All the sites I have checked just show a Watt and connector requirement. If AMD's offering only needs 25 amps then maybe I can do that instead.
