In a PC, the computer power supply is the metal box usually located in the corner of the computer case. In many systems the power supply is visible from the back of the case because it contains the power-cord receptacle and the cooling fan.
The main purpose of the power supply is to convert AC power from the mains to usable low-voltage DC power for the internal components of the computer.
The power supply gives out three different DC voltages to your computer, 12VDC, 5VCD, and 3VDC. These three voltages are used for different components in your system. For example, the 5VDC voltage powers the motherboard, voltage regulators, serial and parallel ports, and PCI and AGP ports.
How Much Power Do You Need?
Each power supply has a certain wattage based on their maximum output power. Common wattages range from 300W to 500W, although for a high-end gaming power supply wattages of 500W to 800W are common. Some units even go up to 1 kW of wattage, but this amount of power isn't necessary for normal users.

A simple AC powered linear power supply usually uses a transformer to convert the voltage from the wall outlet (mains) to a different, usually a lower voltage. If it is used to produce DC a rectifier circuit is employed either as a single chip, an array of diodes sometimes called a diode bridge or Bridge Rectifier, both for fullwave rectification or a single diode yielding a half wave (pulsating) output. More elaborate configurations rectify the AC voltage at first to pulsating DC. Then a capacitor smooths out part of the pulses giving a type of DC voltage. The smaller pulses remaining are known as ripple. Because of a fullwave rectification they occur at twice the mains frequency (in USA it's 60 Hz doubled to 120 Hz). Finally, depending on the requirements of the load, a linear regulator may be used to reduce the ripple sometimes also allowing for adjustment of the output to the desired but a lower voltage.
More elaborate versions used by circuit designers are adjustable up to 30 volts and up to 5 amperes output. These often employ current limiting. Some can be driven by an external signal, for example, for applications requiring a pulsed output.
In the simplest case a single diode is connected directly to the mains and uses a resistor in series with a more or less fixed load to recharge a battery. This circuit is common in rechargeable flashlights.
An adaptor is a device used to match the physical or electrical characteristics of two different things so that a connection may be made between them.
Adapter are device that changes what is passing through, such as a transformer that adapts household electrical current from high voltage (100 to 240 volts AC) to low voltage (3 to 24 volts DC) suitable for consumer electronics
