Yea, i used to love Antec. Have an Antec case and 2 Antec PSU's, but one died on me last month and it was just over a year old = out of warranty. The -5 V SB was causing the PC to keep rebooting continuously.
I picked up a 650W BFG Tech PSU, which has a lifetime warranty with 24/7 tech support. It also has a turbo fan button on the back for when I do some heavy BF2 gaming nights.
