My E4000 pulled substantially more power at 10 336MHz CPUs, 10GB memory,
and two I/O boards.  IIRC it was closer to a kilowatt -sustained- under
maximum CPU load.  It was a staggering amount of power for having no
disks whatsoever, but it was a very dense package of logic.

My E3000 doesn't pull much power.  It's configured with 4.5GB memory,
six 250MHz processors, and four 10krpm disks.  It's a lot closer to the
500W continuous figure you gave.
