The question you have to ask yourself, and that we had to ask ourselves is; do I want to chance running these beasts on a power supply that isn't rated by Nvidia to drive those three beasts. Do I want to take a chance on destroying a beautiful rig, and tanking 3 uber expensive GPU's in the process? The correct answer to that question would be, no you don't.

We were recently faced with that same question, we have 3 GTX-280's in house and currently driving them in dual SLI mode for lack of a suitable Triple SLI approved PSU. That's a sad thing when your looking at 3 of the fastest GPU's in existence and knowing that you won't be able to drive them properly because you have a wimpy 1000 watt PSU, okay so 1000 Watt isn't wimpy, but still to drive triple GTX-280's Nvidia says we need 1200 watts of thumping raw power. Not only do we need 1200 watts of raw power, we need 1200 watts of Nvidia triple SLI approved power. You don't need to look any farther than one of the most trusted names in the business to fix what ails you. The Thermaltake Toughpower 1200 watt PSU is rated by Nvidia to handle 3 GTX-280's running in SLI. In preparation for running all 3 of those beasts we're going to test the Thermaltake Toughpower 1200 running Dual GTX-280's, then after it's had some break in time you'll be seeing it driving our Triple SLI GTX-280 rig. Yes it's been a long time coming, but soon very soon, thanks to Thermaltake, Nvidia, and Bjorn3D you'll be seeing some serious SLI/Crossfire action head to head on the hottest platform known.
