All it takes is a bad cap and some spurious AC floating on top of the DC to
cause the issues here. Had one like that years ago. It used to show up on
and old, very old, version of PCTools from Central Point Software. Maybe new
versions of the program would do it too.

As to PSU testing, well I do not know of any "reasonably" priced
testers, which would do anything useful. A good tester would have to
apply load to all the sections of the PSU and be left on for a while,
looking for voltage levels and have some logic to trap departure from
nominal.
I use car headlight bulbs for load testing on both 12 and 5 volt rails.
I don't bother with the 3.3v one because it is derived from the others.
A 65 Watt bulb will draw about 5.45 amps at 12 volts and the same bulb
will draw about 2.25 amps at 5 volts and consume around 11 Watts.
I will leave you to decide how many bulbs to use !!
Never assume that a new electronic product is functional. I have
seen enough NEW things that were bad and wasted lots of time looking
for something else. Once I even got two new devices that were both
bad and almost pulled my hair out, as you certainly do not expect
both to be bad :-))

I agree ! The chances are that the new PSU is bad ! I few years ago I
remember an incident when a whole batch of PSU were duff. One of the
operators on the factory construction line was applying heatsink paste
but not putting the mica insulators under the power transistors !!
