The system wouldn't power on - only a faint PSU click. Reseating the GPU and RAM, plus holding the power button, brought it back (temporarily).

The earlier fix didn't last. Eventually, the PSU gave up for good and had to be replaced. The true root cause revealed itself after a few false recoveries.
