I put in anatec 330tt psu and a 2100xp on a westerD 80 gig 8meg cache on an abit kt7a board, when i overclock it post then reboots it over clocked great with my 400 watt generic psu and 1600xp, would the psu do this? i thought antec psu were some of the best? i know its not the ram, mobo, hard drive, vidio card, sound card, nic. could a cracked core on the cpu do this (i thought it wold not run if the core was cracked) it runs great at 133 fsb just not any higher.
