possible problem!

psu isnt as beefy as i remember, 12V rails are looking like this:
COOLMAX 550W
12V1 = 18A
12V2 = 18A
12V3 = 15A
450W on 12V total
558W all voltages combine

is that enough to power a 5870?

(copied this from my other thread, gotta get this answered before i buy @ newegg)

Looking through the info from ATI and SAPPHIRE, max power draw for one is 188W. @12V, thats 15.67A max. I should be good to go besides my psu being crap?

I wouldn't trust the numbers given by Coolmax.

You may hook it up and it will run, but I wouldn't trust it. You'll probably be stressing it to the max. and when cheap power supplies blow they usually take other components with them.
