How to define energy consumption of computer's components

I don't think you can with Everest. You'd need something physical, like a Kill-a-Watt meter, but I could be wrong.

You could monitor the individual voltages being consumed with a power meter.

i think the op means something like this



everest can pull data from a sensor on some boards to tell the current wattage of the cpu, but not all boards have the sensor

How accurate do you think that is I am not sure if those sensors tells the real amount of power used. The best way is to get a kill o watt meter. To figure out each component what you do is take every component out of computer just boot with the bare min get a reading then start adding 1 component at a time and take a reading each time at idle and full load this is the only real way to do what you are asking.

that'll take a long time...

Yes it would but it would answer his question lol.
