I have NO specific knowledge of that PSU.

However, it seems likely that a "modern-sh IDE disk" in unlikely to be 
enough load.

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.
