Thank you for everyone answering my post.

I found a solution compatible with my needs.

I get by with the watt rating stamped on the appliance.  If it's using more
than that, it's probably getting hot, trips a breaker, and won't last long
anyway.

Have you ever validated that method by actually measuring to see if
what is stamped on the device is even close to what is actually used?

Not anal enough I guess.

The nameplate is a maximum, the actual consumption could easily be a
fraction (well under half) of the nameplate rating.  Using the
nameplate is a good first approximation, and certainly won't be an
overestimate, but an actual measurement is going to be much better in
most circumstances.  In the case of the OP, the power supply input
power rating of his server isn't going to be anywhere _near_ his
actual consumption.

I've got golf cart chargers with a 1.2KW nameplate rating, care to
guess what's the actual KWHR consumption of them when charging
typically-discharged carts overnight (12 hours)?  Would anyone use
14.4KWHR as an answer?
