Yeah, I figured the adapters would take care of all that, and go from there
as long as it was backed by a strong, and stable enough power supply.

Plus, Tyan said there's some extra signling or feedback the board gets from
the atxges -- hopefully, if so, that's in the eps as well, or.....

it's covered in the Enermax supply.
Because, funny you should mention Enermax. I bought one in the wee hours
this morning after running across their line of supplies on a company out of
Japan's site. That listing sold me on good power supplies -- plus the bad
review I read about the one I had bought for 29 bucks -- it's 580w so may
put it in my old atx. I searched for the best price, and came around to
this nifty unit:

It's on the way to me as we speak. And I've got a new retail jones in terms
of power supplies. These things are cool (pardon pun). Smooth, clean,
stable power. Feel like Tim the tool man -- rawww, rawww, rawww (or
something like that).
