2900XT is has around 210w TDP so 12v@17.5A

8800GTS has a 145w TDP so 12v@12.1A

8800GTX has a 180w TDP so 12v@15A

Real-world power consumption is less though. However, these are at stock speeds.

so i could run a stock 2900xt or an 8800gtx on one pci-e 6 pin connector, seeing as it puts out 18 amps?

A video card can only draw 6.25A per 6-pin PCIe connector. The question is flawed...

If your question is if a 2900XT can run on a 600w GXS with its rail layout, then answer is yes.

dont listen to these kiddies, the OCZ gamexstream is an awesome PSU. It may not be as good as the corsair, seasonic, silverstone's or PC@P, but it gets the job done with little ripple.

You have forgotten to factor in the power supplied by the PCIe x16 slot which i believe is ~6.25 amps.

ahh, good call. so i would have enough power to run it, but obviously not in an sli configuration . but, this means i could run 8800GTS's in SLI.

The OCZ GameXStream (Based on the FSP Epsilon) is a decent PSU. However it DOES suffer from serious ripple under heavy loads (as showed in several reviews, including by jonnyguru.com).

The total max load on the 12V rails combined for the 600W GameXStream is 44A (this used to be on the FSP website for the identical 600W Epsilon, but has now been deleted). Paul, substracting only 2A-3A per rail doesn't cut it. It doesn't work that way. You have to dig for the specs (which sometimes isn't easy).

Obviously the 600W GameXstream cannot deliver more than 50A on the 12V rails (600/12 = 50). Then, there is power needed on the other rails. Thus, the 44A I mentioned does make sense also by deduction this way.

I would not hang SLI 8800GTS on a PSU that suffers from ripple at heavy loads. Yes, it will run, but the pair will load up that PSU quite a bit, and life span of your parts will be shortened.

Personally, I'd be on the lookout for a new PSU (I am myself... need to replace my 700W FSP for the same reasons).

A good choice would be the Silverstone Olympia OP750, which can be found for around $150 (750W, 60A single 12V rail). http://www.case-mod.com/silverstone-...31.html?src=fr

Plus, PLEASE DO NOT call other people names when they try to help you!
