Alrite guys,

I havnt posted in a while, but i more or less read everyday. I know abit about computers, but when it comes to powersupplies it becomes abit complicated.

Right, as you can see from the above question "Would A Thermaltake ToughPower 750W Powerfull Enough For 2x8800GTX's?"

I know the PSU has quad vrails and a max of 60A output, but is that enough?

I plan to run:
E6750@3.2ghz
2gb PC8500+
Asus P5N32-E SLi nForce 680
2x8800GTX's
1 Hard Drive

And, as most of you can see its going to be used for gaming and an odd bit off Rendering now and again.

Shouldn't be a problem. I think under full load with a OC'd Quad system, it doesn't go over 600W and you have plenty of amps on the 12v rails so it's fine.

Yes, good to go.

As I just posted in another section, I have the Q9450 @ 3.4, 2x 8800GTXs (Ultra speeds) and other stuff (3x HD, watercooling, 2x DVD-RWs) running with main psu at 380 watts fully loaded, and my TT power express at about 150 watts running the second GTX.

Total wattage comes in about 550ish to 600. Figure an 85% effiency for your psu, and you still have some room.

The TT Toughpower 750wt is well capable of powering what you have. I personally have a Toughpower 850wt, but the only reason I bought it was because it was on sale for less than a 750wt.

I have the same PSU now and after running a couple of PSU calculators, it's plenty for an SLI setup.

This one you can check http://extreme.outervision.com/psucalculatorlite.jsp
