If it is a switching PSU you'll propably need to load it
in order to have it function properly. I always use an old
defuncty HD for this purpose .....................
Chances are that if the load is not large enough it will shut
itself down, while it may still be a OK PSU.

Subject: Intermittent(?) power-supply trouble
Hi everybody.
Still working on those MIPS RISComputers. I've gotten all three to power-up
and self-test at least once.
The one that's giving me problems came to me marked "bad power supply."
Not
being one to believe the markings, I tried it, and it powered up fine, did
the whole self test, and (due to the lack of any disks) just set there, as
you'd expect.
So here's the deal. I powered it off, and then back on. The second time,
it didn't seem to be getting any power at all -- not even fan-buzz.
Would I be right to suspect a loose joint or the like? Is there anything
else that might cause the power supply to work sporadically?
What's the best way to attack this and get the power-supply fixed? Should I
just dig out a multimeter and start checking connections?
Regards,
Chris
