I think my power supply will handle this setup with 2 gpus. Its runing stable with 1 right now. What do you guys think. I know if i want to go 3gpu then i need 1000watt or more, but there is no real gains in gaming that ive seen from having 3 gpus.

850watt ocz rated to 80 percent effency

The lowest wattage PSU I see on the list at SLI Zone is 950W, so I'd be skeptical that 850W, especially that 850W PSU would handle it well.

It's possible it will work, but I wouldn't bank on it.

That GameXStream PSU you have linked does not appear to be 80+ certified. If you end up buying a new PSU, make sure it's 80+ certified and has Active PFC.
