I'll be interested to see what my new machine (Athlon 2800+,
.5GB RAM, 2 200MB Maxtors and 3 PVR-250 cards) will suck
down. The Kill-a-watt is waiting. :-)

Well, you could move. Not all states have the stupid enviro
laws like the PRC does. I pay < $0.065/kw in Nebraska.

That might be the problem. 3 drives spinning constantly
will use a fair bit of juice.

Somewhat high, especially for a Tbird. A 1GHz Tbird uses
about 54W. If the core voltage is the same, then your
1.3GHz shouldn't go over 60W (guessing), if the voltage was
dropped by AMD then it will be less than that.

From what I remember Intel CPUs use a bit more power than
an AMD for the same performance. But I never have paid
attention to Celerons.
