help! psu problem?

thank you very much, i read one review from an off the wall hardware site that said it was a good psu and the newegg customer reviews weren't that bad but i now understad what your saying about the amps required.

After browsing that list i'm leaning towards the antec truepower trio 550 or the silverstone 600w. My setup is all black, but i've never owned anything silverstone or a modular cable'd PSU so i don't know the ups an downs of that.

If you have any advice as to which to pick please let me know

btw very useful list!

I went ahead and ordered the Corsair 520w model which should be plenty for me. It never really occured to me that more wattage didn't necessarily equal more amps in computer power supplies; I'm an industrial electrician who plays with nothing but high voltage AC at work so the whole multple dc rails powering the same thing never occured to me as phase to phase in AC = very very bad and i just assumed 18a would be plenty.

Thanks again for your help, but i have one more little question; The amp rating for the 12v rails on the corsair is listed at 18(same as the cooler master i have) so is just having that 3rd rail what gives it a 40a rating and does the pic-e plug or the pci-e bus deliver the majority of the power on the upper graphics cards? My old pci-e 6600gt doesnt require a seperate plug is why i'm asking.
