Actually, I don't think I've ever plugged in a newly-acquired classic
computer in the last 10 years, say, without inspecting it inside and
testing the PSU if at all possible.

I don;'t do it _every_ time I turn the machine on, sure...
Basically, the times I do said inspection/test are :
1) When I first get the machine
2) Adter a long time (months/years) of non-use
3) After any other work or repair in the PSU area
4) After moving the machine a significant distance (e.g. taking it to a
computer club meeting or VCF (I wish) for a demostration). Things can
shake loose and short in transit.
