What power supply will power this setup without problems? Also, I might add another 7900GTX so make sure it can power two video cards. I really dont want to buy the 850 or 1000 watt ones but if I have to I will. Ill probably have the Big Typhoon cooling my CPU and maybe 2-3 case fans (1x 120mm and 2x 80mm). Maybe throw in a couple cathodes. I want a PSU that will last me a while hopefully. And could also power a G80 when it comes out. I want it to last me a couple years. Budget under $300. I found one myself but can't verify if its any good:
Will that power everything mentioned efficiently?
