I read up some specifications requirements for GTX 285 is that it needs at least minimum 550W with 12V current rating of 46A and CM RP Pro 650W only draws 45A at 3x12V rails.

Previously i had some probs OC'ing my GC where when it goes further than 660-665/1514/1250 (factory cloak at 648/1478/1242), it will crash my games or auto restart my comps.

Is it probs with the 12V current ratings? I've seen Corsair TX650 has single 12V rails with 50A current rating..


I will say step up. I burnt a 550w with a 9800GTX (Folding 24/7) but the PSU I had only had x2 12v rails. I stepped up to 730w x4 12v rails and have not had any problems. My second rig(Sons) has a 440w x2 12v rails feeding a 9600GT with a P-D 940 (Power hungry CPU) and during games it does the same thing as yours so I will add another PSU to it later. Figure in the CPU,Drives,Fans,Lights,amount of Memory ,etc. Asus sight has a very good PSU calculater and I now believe in more is better. Just to be safe...
