Dual Athlon MP 1U units

Hi,
I do know for a fact that 300W PFC power supplies will work for dual AMD
systems with up to 3 GB of memory and dual IDE HDDs. The caveat is that
300W will not drive AGP cards. Assume an extra 110 W for AGP,
especially for high performance cards such as ATI FireGL2. BTW --
Certain high performance AGP cards will not properly work with dual AMD
systems -- even when using the mem-nopentium option in LILO...
PFC power supplies are standard and are required for certain
international deployments.

Are PFC (power factor correction) power supplies standard, or something
special wrt providing only required power and therefore less heat? A
vendor told me that a dual 1900 Athlon on Tyan 2466 mboard can be run in
1U
if done with a 300w PFC power supply. Do they know some great secret,
or
are they stretching physics?
PS: AMD shows one vendor's case approved with the Athlon MP running at
all
available clock speeds, i.e. that would include 1900+
