Can the BFG 6800 Ultra OC card work with a 350 W PSU ? I see in the BFG kit that there is a power connector. I bet this is for the fan on the card. I am planning to get this card, but the PSU that I have right now is a 350 W one. I am wondering if I havfe to upgrade the PSU. The card does have a spec which says a 480 W is recommended. What do you guys think ?
