I know we went through all of this several months ago ("Do the Commodores
really need the 9VAC?"), but my 128D has an AT power supply in it,
therefore is not feeding the system with 9VAC, and is functioning
perfectly well.

I've even pulled the PSU out of a 1571 and use an external Molex from the
AT PSU in 128D to power the 1571. In my mind I say it is more efficient.
No empirical proof of this, however. :)
