Power Supply Wattage? At least 300Watts for an AMD.... My buddy had this. As I have mentioned in several posts in the last few minutes, he had it running fine in Winxp, and could surf and so on, but when he ran any games or high proc usage apps, the thing would eventually bomb. Would freeze up and the sound card would just continue to buzz (As if repeating the last note indefinitely until we powered it off) He checked and thought his PSU was big enough, but it was not. Upgraded to a 350W PSU and has not had ANY problems since. -TAL
