I dont' think computers use that much power (least normal workstations
anyway) to bring up or down your utility bill much, so couldn't you
just leave it on as is and just shut off your monitor until your ready
to use it again?
I used to do that up until about a year ago. Since then I think I have
noticed a reduced utility bill, but of course that's not really
evidence as there are other factors, including lower rates because of
the drop in oil prices. This is an i7 system with an Nvidia card, an
SSD, a 1TB SATA drive and 16TGB of RAM, so probably above average for
home workstations in terms of power consumption. The monitor is a 23-
inch HP LCD.
Well, I dunno, 16 tera gigabytes of RAM (you said 16TGB) is a hell of
a lot! I've never seen a mobo that could handle that. :-) Must have the
cooling system from hell in there!
If there were an easy way to measure it I would :-)
If you have a clamp-style AC ammeter, you can get a widget that you
plug into your outlet and your system plugs into the widget. The widget
splits the hot line out separately. You put your ammeter around that leg
and measure the current. You can compute your usage using Ohm's law,
e.g. if you measure 2A at 120V, that's 240 VA. If you want it in watts,
your average computer has a power factor of about .8, so that'd be 240
times .8 or 192 watts (or so).
Just an idea.

There are a number of devices that will do the calculations directly.
A page full of them is at
http://www.ebay.com/itm/like/281148981683?lpid=82&chn=ps&ul_noapp=true
and there are a number of devices of similar function under the
trade-mark Kill-A-Watt
but somewhat more expensive. No need to connect an external volt meter,
which is
a bit dangerous.
