Re: 700w PSU handle SLi GTX260 cards?
Needing a ridiculously high powered PSU is a myth. There are actually morons out there who think that if you need a 450W PSU for 1 GPU, then you must need a 900W for SLI. They tend to forget that the power rating takes into account the entire system.
A solid, well-specced 600W PSU will handle 2xGT260 in SLI, depending on what else is in that system.
