[nalla]

I have been worried about this in the future.. Just getting a 3870x2 and if i add another in the future i will struggle with the 620w corsair as i have 3 hard drives, 1 dvd-rw, CPU at 4.3ghz and will soon have watercooling... lol...

I am using the corsair hx620 with a 4870x2 no problems as yet

I'm gonna say you'll be fine.

I run CF 4850's + OC'd Q6600 on a 620 Corsair, and I seriously doubt i'm even close to stressing the PSU.
