Working on a power supply. Just can't toss it without completely destroying it first. This PSU has almost no use and is out of warranty of course. Upon close-magnified scrutiny of the components nothing indicates failure, i.e. bulging caps, burned FETS, broken wires, fuse, etc.
Primary Symptom: When green wire is grounded at main terminal none of the computer peripherals receive 12V, 5V and/or 3.3V.
The 400V cap is only showing 168V(dc) (waiting on cap tester now). Thinking this cap should be somewhere around 350-375V. This is the first discrepancy I find in circuit.
Question: If cap is good what in the circuit would prevent it from charging to an estimated 350-375V?
I am getting the 5vstdby as annotated on "Bottom" (bottom left;orange).
I have added a few pictures indicating general observations from probing.
