I have NO specific knowledge of that PSU.
However, it seems likely that a "modern-sh IDE disk" in unlikely to be
enough load.
OB_useless_nostalgia:
In the old days, we used an automotive headlight bulb. That also provided
a lot, even excess, light on the workbench. Since my microcomputer days
overlapped the period that I ran a Honda car repair shop (until 1980), I
used to save any dual filament (High/low) bulbs that we replaced due to
ONE of the filaments burning out. I made an aimable mount for my
workbench load out of an early VW headlight mount.
