that's about right. my dual 240's peak at about 250 running
two copies of stream and one bonnie (2GB, 40G 7200rpm IDE).

nothing else counts for much. for instance, dimms are a couple
watts apiece (makes you wonder about the heatspreaders that
gamers/overclockers love so much), nics and disks are ~10W, etc.

iirc my dual xeon/2.4's peak at around 190W (1-2GB, otherwise same).

hey, to marketing planners, massive power dissipation is
probably a *good* thing. serious "enterprise" computers must
have an impressive dissipation to set them apart from those
piddly little game/surfing boxes ;)
