I have a antec 350 smart power pS in an antec case. I had trouble with the PC freezing all of a sudden. I suspected PS. I changed it to a thermotake 430 and seems to be fine. I was running a 64 bit amd 3200 with 1 gig of corsair mem 3200 and a 6200/256 mem geforce Video card.I had the 250 gig HD and Dvd Burner, floppy. I thought the smart power 350 would be enough watts for the system. Has any one had any problems with this PS. Thanks Bruce
