A Power Supply is a hardware component that supplies power to an electrical device. It receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires. It also regulates the voltage to an adequate amount, which allows the computer to run smoothly without overheating. The power supplies an integral part of any computer and must function correctly for the rest of the components to work. You can locate the power supply on a system unit by simply finding the input where the power cord is plugged in.
E.g.: All electronic devices like TV, Refrigerator, AC, and more.
