Captainwreck Posted September 18, 2008 Share Posted September 18, 2008 I was just wondering if my 750 TX would be enough power for 2 280's in SLI. See my spec, my cpu is overclocked, and i didn't list it but my ram is at 1.9 Link to comment Share on other sites More sharing options...
JoeBob Posted September 18, 2008 Share Posted September 18, 2008 Two GTX280s would probably need about 360W. (according to XBitlabs measurements for one card, 180W). Say about ~140-150W for your OC'd CPU and let's add ~50W for the rest of the stuff. So I'd say you're looking at about 550+ watts total load worst case. That leaves some headroom. The fan will probably ramp up a bit, but the PSU should be good for that gear. Link to comment Share on other sites More sharing options...
