Need Very Powerful PSU

I'm looking for a top-of-the line power supply that will deliver enough watts for my setup, but it doesn't seem I'm having too much luck, as I have no experience with power supplies. Ireally don't want to short anything or waste money, so I am definately open to any advice :]

Setup:
Motherboard: 790i nForce

CPU: Intel Core 2 Extreme QX9770

Memory: 8GB (4 x 2GB) DDR3 2000 (PC16000) Corsair Dominator

Video: 2x EVGA GTX 280 HC16 Edition (possibly 3 if any PSUs will even support this?)

Sound: Creative X-FI Elite

HDD: 2x WD 300GB Velociraptors


PSU: __________

I'd go with a Thermaltake Toughpower 1000-1200W.

1000W
1200W

there you go, top of the line, very powerful.

I heard the 1000w PSUs will work with tri SLI and possibly even the 600w, too. The Toughpower's just didn't seem powerful enough to me.. I don't know why Im so skeptical about all of those though/ I've been looking around everywhere, including johnnyguru, but I get so much mixed information. Like on the Slizone psu list or w.e, there are only 5 or so listed and I wanted to know if it HAD to be those or better. Haha yah i am lazy but Ive been looking for one for almost two weeks now, im just worried something will go horribly wrong if i dont have a good enough power supply. Tbh, I don't think its worth one of my kidneys for the Guardian, xD

The certified PSUs for two 9800GX2 cards are listed here:

The list should be good for GTX 280 SLI too IMO because the power consumption is very close. For example a Corsair 1000HX would handle two of those OK, or a Toughpower 1000W.

I've seen an article where some guys in Belgium used a Toughpower 1500W to power FOUR 9800GX2 cards.

I guess a 3-card setup with GTX 280 needs something in the 1200W range indeed. There's a TurboCool 1200W for example.

The Toughpower 1200W is also a good PSU, has the required connectors, and it's cheaper at only $400

You could save a lot of money with a Q9450, 780i and DDR2.
