======= Here is Guru3D's power supply recommendation ==========

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina. Source - http://www.guru3d.com/articles_pages/evga_geforce_gtx_680_classified_with_evbot_review,8.html

Does RoseWill compare to Corsair and Cooler Master?
 
No!Cooler Master PSUs tend to be pretty crappy the ones that are actually reliable aren't extraordinary for the price. The Enhance models are especially good. All of the Silent Pro series are quite good.The rest have been tested time and time again and results remain the same straight garbage !You would think since they provide such great cases they would provide great power supplies.I am sad to say didn't happen that way. :(
 
No it does not but not all Rosewill power supplies are reliable as far as brand goes no that is not how you pick a power supply IMHO anyway.Because as much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have an or several dedicated video card(s). As a general rule of thumb, you are aiming for the highest number on the 12V line.

I've seen dual SLI GTX 680 benchmarks and at 100% system load, the total system power consumption is almost 1,000W.
