I'm looking at either a corsair 750w TX or an ePower Zumax 850W to power 4 8800gt's. the corsair is a single rail and the Zumax is 4 rail.

will either of these do just fine? this is a dedicated folder only, no gaming. 1 hdd, 2x2gb sticks of 1000mhz and a Q6600 with liquid cooling.

what do you think?

TIA
