It's not the through hole tantalums either.
5V rail is at 5.1V
-12V at -12.1V
+12V at +12.1V

Straight up not having a good time today. Gonna try to funnel my emotions into fixing this mofo.
I checked the Command Module separately with the AT supply again. It's dead, Jim. Maybe independently of the PSU and the PSU was iffy all along. Which I did not notice because the squeaky sounds it makes were muffled by the fan noise. And the faulty 24V line is used only for the fans and I never checked it.

Gonna focus on the PSU first, since I got it apart.
Here's the 24V output.
The 24V output is supposed to deliver up to 1.5A. An LM350T linear regulator is used for regulation there. This is its input. Second capture is a power on-off cycle. That tracks with the squeaking that can be heard.
150 Ohm ohmic load on the 24V line at the input of the LM350
I am officially ADHD+.

It took only ten or so years after the Asperger's diagnosis to figure that one out and get it in writing. Geez.

You may already know that I've been hacking my own biology.

One thing I'm really not happy with is the sex hormones my body expresses on its own. It messed up my life. Since August '24 I've been on HRT. I used Cyproteronacetat to supress the production of testosterone. CPA is the go to T-blocker in my country. However, this stuff comes with a lot of risks and side effects. It affected my mental health after a few months, so I had to stop the blocker and find an alternative solution. I finally managed to get my health insurance to pay for GnRHa therapy. Had my first injection last week.
