I think I eliminated that. Even when I disconnected
the hard drives, DVD, etc., the system wouldn't POST.
I've also used the same PSU to drive a pair of 2800MP's
on an S2466 loaded with 4 SATA drives, a DVD burner,
and 4 GB of RAM.

The Barton 2800MP's have a 266 MHz FSB. Probably just
recognition by AMD that every Athlon MP motherboard uses
AMD's 760 or 760MPX chipsets - which support only 200
and 266 MHz FSB.
And yes, the multiplier is locked.

Turns out my price comparison was wrong anyway. I was looking
at prices for the Opty 142, not the 242 - which costs significantly
more.
