A friend ended up giving his bad PSU to me, the Antec Truepower 650 Trio.
Let me tell you, I hate these PSUs that use SMT (hate SMT in general, makes it hard to replace devices). I hate these PSUs that use these riser cards that tries to pack more devices in the same amount of space too...
Well, it looks like this PSU the 5VSB is working but will only blip the normal rails when power is attempted to be turned on. Suspecting a fault condition... I was looking for the TPS3510 or similar chip as a place to start debug but...OUCH it's probably on a riser board... OUCH it's a SMT riser board... GRRR!!!
This also looks like a primary side control switcher like the UC384x but the controller is on a riser card too Can't tell what controller it uses other than it's 14 or 16 pins...
I guess this might be relegated into the spare parts pile, though it may be a PSU worth repairing and using as a spare...
Looks like most of the caps in this are OST branded, the main filter cap (Active PFC) is a Rubycon oddly enough. I'm not sure why they made the choice this way...since the smaller caps are under higher stress, wouldn't it make sense for them to be the quality devices? World may never know...
