This is tricky to answer, because the Iyo seems to require a PSU with a spec
better than that allowed for by the ATX spec.  As such, it's really a case
of "suck it and see": I've had "high quality"[1] PSUs fail to work (while
being fine in a standard PC), while more "standard"[1] units have been OK. 
When I looked at the outputs on test equipment, there was nothing obvious
between the two PSUs in question.

If you have a spare PSU, then try fitting it and see if it works.  If it
does, then box it all up and cross your fingers...  250W should be plenty.
