if you inject voltage into a running psu you have a risk of messing with the feedback pin.
you could remove the stanby circuit output rectifier diode and inject power there to see how much current the psu draws.
do it with the psu unpowered....Leave a comment:

does it use a TNY chip?...Leave a comment:

unlees you can read capacitance, ESR & Leakage you cant really test a cap...Leave a comment:

dab radio's are a pain in the ass,
not only are there over a dozen modules, every radio uses different firmware to configure the display and controls....Leave a comment:

o.k. - 30years minimum - probably main caps.
here's a manual:

how old is it?
maybe the main smoothing capacitors have dried out....Leave a comment:

you can get bad caps on high frequency circuits like switching psu's in under 5 years these days.
specially as the frequency the things run at keep increasing.
it used to be that switching regulators ran at 25-70KHz,
now some are upto a MHz!!! those arent even suitable for electrolytics, you need ceramics and polymer on those!!...Leave a comment:

i would check the 5v standby with different loads to see if it's faulty,
it should give stable 5v upto atleast a 2A load
did you re-cap the 5v standby section?...Leave a comment:

the controller can be identified by software or checking the boot logs.
as for win11,
it looks like it also has problems with some wifi chipset too now!Leave a comment:

Phison make the controller used in the other names on the list.
most harddrive/ssd makers dont use their own chips.
i will give you an example:
Integra SSD drives.
the C series uses a Silicon Motion SM2258XT,
the P series uses a Phison S11,
the V² series uses a Marvell 1120....Leave a comment:

compare the example to your psu - the PG output doesnt have much to check...

the 5v standby is independent and should always be present on a psu,
the motherboard controller should use it and a clock - usually 32.768khz to monitor stuff and power up the psu.
(and then monitor PG and maybe voltages to bring the system out of reset)
you mentioned a psu that switches itself on - thats usually a bad opto-isolator.
as for fan control,
i'm not a fan of that, the psu is usually responsible for keeping air flowing through the machine unless it's a gaming rig.
if you slow or stop the psu fan the motherboard or gpu could overheat...Leave a comment:

the shit just got worse!
multiple controllers and isssues

missing "PG" signal from the supervisor chip
it's used to reset the motherboard once the psu is stable...Leave a comment:
