I believe some PSU's need the load between 5V and ground, others between
12V and ground (or some other rail), depending on the design of the PSU.
I tend to use an old scrap hard drive as a dummy load for PSU's with 5V
and 12V rails (plus it gives an audible sound that something's
happening :)

It takes about
5 minutes to test a PUS on dummy load. No longer.
...if you have Tony Duell's workshop and tools available.
I, for example, have few suitable dummy loads at hand. I have a load
resistor which came form an old Sun (4 ohms), though I'm not sure
whether it's between 5V and ground or 12V and ground - it I suspect the
latter, since it looks more like 36W than 6?W. (It could even be
between 5V and 12V from what I can tell, though that would be Weird.)
