Just setup a new system last night consisting of an e6300, gigabyte ds3, x1900xt, 2gb patriot ddr2, wd raptor 74gb sata, wd 320gb sata, nec 3550a and a regular lite on dvd rom. clocked it up to 3.15ghz and was running 2 instances of prime 95 for 2 hours and went to bed while i let it run. i wake up and the computer is off. switch an antec true power II 550 watt and it boots fine so i try the s12 again and nothing. did i just get unlucky with it dying because i had to rma an s12 before for comatibility issues with a dfi nf4 motherboard.
