I am looking into a system with an i5 750 core and a GTX 460 (768 MB version). The PSU I'm interested in is the OCZ ModXStream Pro 600W. My concern is the amperage - unlike the more expensive Corsair 650W, the OCZ pushes 25A down each of two 12V rails. Will this amperage be sufficient for my graphics card needs? I do not intend to SLI this card ever.
that PSU is more than enough to handle the GTX 460 with no problems at all. that's 50 total amps on the 12v rail(s). While a single 12v rail may be better than 2 12v rails, it usually makes no difference when it comes to quality-ish PSU's and that OCZ is semi-decent..
