ABSTRACT:
A power supply for automatically supplying a proper voltage to a central processing unit, includes: a voltage detecting pin of the central processing unit for outputting an operating voltage indicating signal; a selector for causing corresponding operating voltage to be inputted to the central processing unit by sensing the voltage detecting pin state outputted by the central processing unit; a power supply which supplies a proper voltage to the central processing unit; and a controller which outputs a control signal so as to supply the proper operating voltage to the central processing unit by determining the type of the central processing unit.
