Default Re: AXP AXP-500P12P 3.3V line issue

Update: After some playing with the load resistor for 3.3V (50ohm) the psu worked for like ~1h on the same P5PL2 with very stable 3.3V line @ ~3.4V but at some point it switch off. The mainboard standby led is still on and the 5VSB looks fine at 5.05V, the PSU does the same 1-2sec fan spin and will switch off. It will do it on any board run for 1-2sec and then switch off. I even re-installed the old S20C40C but that made no difference. Primary caps Transistors etc look fine.
