You need an electronic energy meter plugged between the AC plug and your pc.

But any big box home depot store oe electronics store, should have a similar product.
With this you can calculate exactly how many kWh your pc is using.

The power supply (where the plug goes in) on your computer should have a sticker with the rated Wattage of that supply. Mine, for instance, is a 500W power supply. That means at peak usage it will use 1 kW.h every 2 hours.
Now, in reality, your computer uses about 60% of the peak rated power of the power supply.

Most run about .35 Kwh.
It depends on how much hardware you have installed and the speed of your chip. 350 watts total is a good average.
