Only, not really with PC power supplies anymore, because both EU
and USAs "EnergyStar" have requirements for power factor correction.

So V*A=W is a pretty good approximation these days.

And speaking of Intels small motherboards:  I have a D2500CCE board
and apart from some weirdness related to the videomemory not supporting
32bit writes in character mode, it works ok for me.

Never attribute to malice what can adequately be explained by incompetence.
