After fixing it the first time around from https://www.badcaps.net/forum/showthread.php?t=24113 the old venerable PSU has failed again! Well, not totally dead. I had been powering a Prescott 3GHz with 5 HDDs with an onboard GPU. It had trouble powering up the system at first (would cycle) but eventually it would come on.
However it had came on the last time. Now it won't power up any more. Yes I think this system might have been really pushing a 300W PSU.
Anyway, 5VSB still looks good, and... if I short the green wire to GND, it will turn on just fine when the PSU is not plugged into a motherboard!
Swapping this PSU with the repaired SP400 powers up the P4 machine so something strange is going on... Perhaps one of the secondary diodes gave up?
(BTW Anyone seen PeteS in CA recently? Haven't seen any of his insightful posts in a while.)
