Apparatus for measuring average power consumption of computer system

An apparatus for measuring average power consumption of a computer system, comprising:

• an electric current sensor capable of transforming an operating current of the computer system into a voltage signal;
• an analog-digital converter connected to the electric current sensor capable of converting the voltage signal into a digital signal indicating a value of the operating current;
• a micro controller unit connected to the analog-digital converter capable of receiving the digital signal, and multiplying an operating voltage of the computer system by the digital signal from the analog-digital converter to get an instantaneous power consumption of the computer system, then averaging a plurality of the instantaneous power consumption readings taken over a determined period of time to calculate a value of the average power consumption of the computer system during the determined period of time, and converting the value of the average power consumption into a display-driving signal;
• and
• a display module connected to the micro controller unit capable of receiving the display-driving signal and displaying the value of the average power consumption.
