Looks your problem fits on the power supply!
I have one 1230XA myself with an PC/AT PSU (200 W), and everything runs fine!:-D
A time ago I test a orig PSU with my Miggy: guess what happened? Instability, reboots from nothing, errors in reads and writes....:boohoo:
Almost destroy my HD partition!:boohoo:
Buy yourself an old PC/AT PSU (cheap an much more reliable than ATX ones). You'll need some ironwork, but is easy.:rtfm:
[ ]s :-D
