Right - but on a transformer, the two are linked, because of the 
resisistance of its windings.
Normally, you have a full-load voltage specified, and an off-load voltage. 
If you're running it at a light load, you're closer to the off-load spec 
than the full-load spec.

But to get back to practical matters, I've looked up the specs for a random 
picked 500VA transformer. Full-load voltage and off-load voltage only differ 
by 4% - we certainly can live with *that*.

Wait a minute - were you talking about a regulated AC PSU, and not a simple 
transformer?
With active electronics inside that regulates the amplitude of the AC output 
? (But these have other problems.)
