Is 650W enough for GTX 460 768MB SLI + Thuban OC'd?

post #1 of 41
Thread Starter 
AMD Phenom II X6 1055T 4.1 GHz at 1.48V (2 cores disabled)
GTX 460 768MB SLI OC'd to 900MHz at 1.050V
Four 230mm .35 ampss
5 fans .53 amps
2 T3 Sammys
1 SSD

Would a XFX 650W power supply be able to handle this when everything is at full load?

A bunch of people told me an XFX 650W was enough but I recently had to RMA it because it started smoking. I don't know if it was just a faulty PSU or if it was handling too much load. So...recently, I disabled two cores to reduce the power usage a bit.

Also does a OC'd GTX 460 at 900MHz at 1.050V consume as much power as a stock GTX 470?

That should be just fine unless you've got a faulty PSU. No need to disable cores.

650w is really pushing it with OCed CPU, GPUs, I would say 750w-850w is a better shot.
Smoke? 460 sli OC is a bit harsh.
