I recently read up some articles about how to reads the 12V current rating for certain PSU. I am now using a Cooler Master Real Power Pro 650W and my rigs specs is as my siggy.

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..

You should be fine with a 650W man

i sees that you use corsair HX620.. which i think has more than 50A on single rail right ? but mine is 3x12V rail with 19A each.. and 540W total on those 3 rails plus 650 continuous power. I've check it only produce 540W/12V = 45A, and actually i already sold my Galaxy GTX 285 and planning to get XFX GTX 285 Black Edition, do you think it will be stable ?

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...

I keep seeing the post about powersupplies and everyone will say its fine but like you, yourself will find that more is better
