Is the kingwin Mach 1 1000w PSU enough to run 2xGTX 480 SLI?

For 1 480 it recomends 600wattt PSU. I have seen some indications that SLI 480s will only draw about 850 watts under peak.

Does the Kingwin have enough enough amps as well?

or 2 5870s in CF? I am not sure about ATI support (its been a while since I have owned an ATI card and before it was driver hell). If I choose ATI how is there driver support lately?

I hate being presurred to buy a product but I have to because my 280 took a dump and i put my other one into wifes rig!

well, it should be plenty for 2 x GTX480's as long as it can output its rated 80A on the 21v rails

2 x 5870, you could do that on a quality 650w PSU (750 is preferable), just remember to totally clean out the NV drivers before installing the ATI cards (if you go this way)

I have such a headache! I have the 1000 bucks to throw down but I want to make a good decision. I already have the evga 480s on pre-order but I am also concerned about the heat and longevity of the cards and if I go with ATI I am concerned about the support because Nvidia has better industry support!

Damn I hate making choices!

well, you can always wait to see how the heat holds up in a few months or when the AIB's (ie EVGA and others) make custom boards and coolers to cool it better

or the other solution is not care about the 10-15% performance difference and get the 5870's

and about support, what did you mean, drivers (if so, windows or linux)?

If this is the one you are talking about, then yes...you will have power to spare...
