How do you load up the PSU when testing with a mutilmeter? I've caught
one bad PSU with a multimeter but I have another one suspect that
shows fine on all leads. I suspect that if I could load it somehow I
would catch it dropping voltage. What draws 300-500 watts yet is safe
enough to plug around the different leads? Five lightbulbs? I don't
suppose it would matter that the PSU is DC, but can you tell me
otherwise?

I would like to stress what another poster said, that memtest should
be run at least overnight and 24 hours if possible on slower systems.
It performs a _lot_ of tests and each one should be performed mutiple
times.
