IIRC, there were NUMEROUS versions of the IIcx PSU.

My IIcx, which was an early one, bought through Apple's "family and friends" program, had a General Electric PSU.

Later examples include ASTEC, and perhaps several others.

All are externally identical, but their internals may differ quite a bit.
