one of the first two

the third one will not have enough amps on the +12v to run 2 high end cards in SLI, e.g two 8800GTX

I just bought the 600watt one today, and i decided i will not use SLI with two big cards. The 600watt cost me a mere 75.00, and its more than enough for any of my future systems, considering that i upgraded from a 250watt infant!!

cheaper doesnt nececerially = better

a cheapass "650w" may really produce as little as 250w

of course it doesn't mean better, but a more expensive psu would've been a waste of money for the system i have, since i won't be doing 8800GTS SLI, etc.
