Abstract

A device for managing electric power source of CPU, which is applied to detect the consumption of power supply of Central Processing Unit (CPU) by way of an administration module. The invention, therefore, reduces the power consumption through an adjustment mechanism, as long as the power consumption of CPU exceeds a predetermined value, for the purpose of achieving the object of managing working power voltage of CPU.

Claims
