PC accessories

A computer is a useless device without accessories. Various PC accessories are available to enhance the performance of a computer. Some of these accessories are required, while others are optional.

The most important PC accessory is the power supply. A power supply converts AC power to DC power, which is needed by a computer. The power supply also provides a number of connectors that allow the computer to be connected to devices such as a monitor, keyboard, and mouse.

A computer case is another important PC accessory. The case protects the internal components of the computer and provides a place to connect the external devices. Cases come in a variety of shapes and sizes, and there is one to fit every budget.
