Probably not that particualr PSU, but I know that some
of the smaller
DEC pSUs used on Qbus systems do not work correctly unloaded.
It wasn't a DEC PSU, but I once fried a PSU by running it with too
little load. (It was a Sun SPARCstation SLC or ELC, I forget which,
and I was using the PSU without the monitor load it was designed to
always drive -
http://www.sunhelp.org/~mouse is a page I wrote up for
sunhelp.org which, among other things, mentions the experience.)
