2 x GTX 680 SLI and power supply requirement

[Dave3000]

I might be upgrading to 2 GTX 680's in SLI from 1 GTX 580. I have an 850w Corsair power supply, used for about 3 years, and my CPU is an i7 3930k. Would my power supply be able to handle 2 GTX 680's with an i7 3930k?

It's plenty with wattage to spare

if everything is stock you easily have well over 250 watts to spare while playing games.

It would be fine.
