My buddy needed a new card so I recommended him to get a 4850. He's had it for a few weeks now and today his computer started turning off while in game. I'm starting to wonder if his power supply can handle the load of the card.
I'm pretty sure 400 watts is more than enough to drive his system but I couldn't find the specs of the ps anywhere online. He checked the back and the ratings are 115V/230V 8A/5A 50-60Hz. Does it deliver enough current for the card? or can this problem be caused by something else?
