I'm planning to add a second GTX580 to my system, but before i proceed with my order i want to make sure that my current PSU will be enough for a Sli setup even if i OC my CPU (which i'm planning to do)

This is what i have now:
PC Power & Cooling Silencer 910W SLI Certified ATX Power Supply 80 Plus Silver
Manufacturer states that the PSU is "NVIDIA SLI Certified (Up To 2 x GTX580)", but i have a feeling that it might be a close call - pushing the PSU to max.


Current system:
Intel Core i5 2500K no OC done yet
ASUS P8Z68-V Pro
Corsair Cooling Air Series A70
EVGA GeForce GTX 580 Superclocked
Coolermaster Haf 922 /w extra 200mm side fan

yes it will be very sufficient, maximum power board of these cards both equals 500W at full load of course, you're PSU is good enough to handle the rest of your components effectively and PC cooling & power silencer is a good one as well :)

Agreed. My system peaks around 680W with standard clocks with the GPUs at 100% load. Any OC could add up to 100W to each component depending on the OC.

If you have two 580s, you'll find there's not much of a reason to OC anything. I never have to.
