Ok, So I'm looking at a psu, and it has 6 12v rails, 4 @ 20a and 2 @ 35a. I'm also looking at getting the EVGA gtx 295 co-op edition. The website says that card requires a min 650 watt psu, pulling 46a of 12v power. My question is, would my card be connected to just one of those rails? If so, wouldn't that mean that the PSU wouldnt power the card? Would I need to find a PSU that offers a 12v rail @ 46a to power my card? I have no Idea how these multi rail PSU's work. Any advice would be much appreciated.
