I need to investigate how much power my linux machine uses per week. I can take a look at the PSU but I would like to know how to calculate the average use of power it takes.

I also need to know how much power a CRT screen use per week.

Do I need to check the PSU Watt unit and Screen Watt usage and just add both to have the results?

P.S. My english is not good, sorry about that!

P.P.S. My question is not related to: http://superuser.com/questions/9946/how-to-choose-a-ups-calculate-power-for-a-new-pc
