This is a reply to a message from here from 2 months ago.   I actually
am running right now off of batteries and the power meter on my inverter
is reading 120 to 130 watts running the computer (with 3 disk drives,
a GPU, an Athlon 3000 not doing much and a few other minor peripherals.)

My power's out because a car smashed into the power pole in front of
my house!!!

Thus it got me to get around and measuring it as you challenged.  My
feelings about the power usage were correct, and I don't think it's
unusual for desktop systems like mine, nor do I think you must be wrong
about your rack mount server, which is probably designed for better
power efficiency.
