Might go SLI...Power?

[cjtaylor0103]

Thinking of going with a second video card in SLI. Specs of my PC below....3 120mm fans also running. Do I need to beef up the power if I add another card?

This calculator should tell you what you need.

700W should be easily enough, TRiSLi with ULTRAS pulls just over 800W

But i havent heard of that PSU manufacturer before so it might be a better idea to upgrade the PSU to a decent one, Tagan, Seasonic, Antec, Corsair, you wany 650W minimum really just to be safe.

That power supply should be fine. 3 12V rails. One at 16, one at 17, and one at 25.

Reviews are all super high as well. It should work. That being said, if it doesn't keep up then upgrade, but I don't see an issue with it.

I tried it out and it seems a little outdated... it only went up to the 6800 series and Pentium 4's as far as I can tell.
