292 Watts X 3 6950s = 876 Watts
Add 300 Watts for Components (for headroom & overclocking)

Total Power Consumption under Full Stress = 1176 Watts

You will not be putting this system under Full Stress most of the time, unless your gaming non stop...

In that case you might even go for overkill and jump to 1500 watts if you don't mind paying a larger electric bill.... (+ $20-$40 / Month)

SILVERSTONE ST1500 1500W ATX 12V 2.3 & EPS 12V SLI Ready 80 PLUS SILVER Certified Active PFC Power Supply ($380)



Dual SLI would be better because you could use a lower wattage PSU and the gain for the third Video Card just doesn't warrant paying the extra cash for the extra power (monthly mind you)...
That was total system power.

A single 6950 alone would never draw close to 290W.

That table is the full system load with one card. The CPU uses as much power as a 6850, 850W is more than enough. Divide the total system wattage in half and you have a good estimate of the 6850's wattage for that system.

EDIT: if that table was showing system load for the card only then my friend's computer would have exploded already. He is running GTX480 SLI on a TX750W psu. There have been no problems yet and its been going for over a year.
He also overclocked

All to their own I suppose. I prefer the HX series though that may be because the HX series that isnt the HX1000W is all based off a new design..... I think I just proved to my self that the HX1000W is not all that great.

Well at least the HX850W PSU is awesome.
