I don't have numbers handy for the IBM boxes, but note that the p680
can go 6 to 24 CPU, and from 4G to 96G of RAM.  Hardly a case where
one number will fit all.  IBM at least *used* to provide power info
on a per-component basis, but you had to get the 'Site Planning and
Preparation' manual for the system in question.  I also know that SGI
has information on amperage considerations for their O2K,  Onyx and Onyx2
rack-mount servers, where you *can* get into the situation where you
have open slots, but be unable to put a high-draw card in because
the power supply for the cage isn't rated for it.

The only way to get "more accurate" info is to line-item each component
and add up the numbers for *your* configuration.
