The calculation I have for under load is 143 watts difference,
and according to the NS Power calculator that works out to $133/year
Keep in mind, part of the goal in this is finding an upgrade. The PIII system
maxes out at 1 GB of RAM, which amavisd can take over half, and growing
in each new version. All other upgrade paths I saw used more electricity than
a PIII generation, so I balked at upgrading for some time.
This is part of the energy conservation process. I'm also looking to stop
my use of a Cisco switch which eats 40 watts, compared to chaining
small consumer switches which use 1 to 4 watts. Desktops are only turned on
while in use, rather than left on. The changes all add up to something
significant compared to where I was, and where I could have been going.
