Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.

So the function of a DC Power Supply is to provide Direct current to various accessories of computer such as Hard Disk, Ram, Picture Tube or LCD, Mother Board, CD Rom/DVD Rom, etc, so that they function properly.
