Re: FSP400-60GLN worth fixing?
Well they have more common things, like the main transformer, the output inductor and of course - the feedback and regulation. The +3.3 V is magamp'ed so that's kinda failproof. If the inductor is designed to saturate early, it can still provide good enough voltage no matter what's comming from the +5 V.
BTW, I took three other, non-FSP units, screwed one somehow (but that was slightly greater work with some operations and transplantations, so I guess problem is somewhere in there), the other two were just fine and very easy work: HP AcBel 300watter (with DC-DC even!) and Delta GPS300FB B or something like that, very nice, simple and airy unit, I like it. One G31 board from ASUS did not like the AcBel much but it was running with Biostar A780L so no prob.
As for GLNs, I have found another 350watter so as soon as I'll have time I'll remove both SB transformers and compare the windings with Malish to test everell's theory…
DM's or other SB PWM's are on the stand-by rail, that is in front of the SB transformer, IIRC next to the primary heatsink. The 6800 should be on a primary daughterboard if memory serves me well?
