Hey, I have a Thermaltek 430W PSU with a 18amp 12V. I am getting a BFG 7900gt. They recomend a 350W PSU with 20amp 12V. Nvidia says it needs a 350W and 15amp 12V. Do I need to upgrade the PSU. I have only 1 harddrive and a dvd drive. Thanks. Could I test it first, or should I go out right away and get a new one?
