I have had 4 Antec PP303X power supplies. (3 in my computer, 1 in my son's) I am on the third one as the first 2 lived very short lives. I have just exchanged for the third and have not even rebuilt my system into the case. I am running a PIII 700E, Gladiac, 1 cd-rom (used mostly for installs), floppy drive, Netgear Ethernet, and SB Live!. Nothing has ever been overclocked. If another one fails I will go with the Sparkle as it is available from the same store at the same price.
