I've missed the beginning of this thread, so I beg forgiveness should
this response be off-base.
To measure the power my computer uses, I use a Kill-a-Watt meter,
at last notice they were available from Amazon. The one I have was
something like 20 dollars, a few years ago. It continuously tells
me the wattage used. alternatively it can report several other measurements
as well (it isn't where I am, so I won't go out on a limb with a list
that may be wrong.)
You plug it into your outlet, then plug the computer into it. Press
the right button on the front to get the measurement you want.
It is reporting that my computer uses around 117 watts (plus or minus
a couple) when running FoldingAtHome on both a six-core AMD and the
Nvidia 750Ti GPU. without the FAH client it would probably be around
half that (I haven't done that measurement).
