I am going to have an Intel i7 965 Extreme 3.2 GHz CPU, Asus P6T motherboard, 2 WD Velociraptors 10,000rpm raid 0, and 2 Nvidia GTX280 graphic card's.
Need some help determining the power supply I am going to need. The GTX 280 alone requires a 550w and 40amp on just a single +12v rail.
A lot of the power supplies people are recommending are multi-rail. The problem with this is that most of them have only a max of about 35amp's on one of the +12v rails. This is lower than the 40amp needed on a single rail for the GTX 280.
The Corsair HX1000 has 2 rails with 40amp each. The problem with that is each rail only has 500w going to it and not the needed 550w.
I am currently looking into single rail +12v designs with about 60amp-90amp. I was wandering if this is as safe as multi-rail with all that power coming from a single rail.
Thank you.
