Yes, it will, I just bought an EVGA Supernova G2 850W PSU (the one I posted, it actually arrived today I just haven't installed it yet), it's replacing an EVGA Supernova B 750W PSU I have now). I'm able to run all I have plus 7 fans and a digital fan controller and the rest of my hardware (you can see the specs of my rig in my signature) with a 750W PSU, I got an 850W so I can overclock with more stability, and because the PSU I just bought has a single 12v rail, and is gold rated AND has a 10 year warranty. Not only that but its capacitors are made in Japan.
Even if it would cost a bit more, the PSU I posted is the best 850W PSU there is, IMO. Just make sure whatever you decide on, it has a single 12v rail.
and to quote SR-71 Blackbird from another thread:
The EVGA is superior to the Seasonic.
The EVGA is made by the best = Super Flower.
