[Poizen22]

are you absolutely sure? did you look at the rest of my rig and what im running/what i plan to upgrade? cuz i realllllllly dont want to buy a new PSU, only to have it it not be enough power... i used Newegg's power supply calculator, and it suggested i should be running something more like 733W... if youre sure, thats fine, just... please be sure? haha
thanks so much tho :] - RK

i could cross fire 3870x2s with my psu and il run sli 9800gtx fine, i may even try to get away with try sli 9800gtx with my silver stone strider 600w, its a great psu i strongly recomend it over the corsair 520hx for the price.
