The power supply changes the 120v ac 60 hz (in the us and Canada) to dc 12v, dc 5v, and dc 3.3 v that the computer components can use. The power supply is rated in power supplied as watts of power.
The power supply converts alternating electric current (AC) into a form that the computer use. It reduces the electric outlet voltage from 100-200 volts electric outlet Alternating Current (AC) to a lower voltage Direct Current (DC) used by the CPU and other computer components.
The power supply generates heat which can be damaging to itself and the computer. To avoid this desktop computer power supplies have fans and ventilation to prevent overheating. In notebook style computers, the power supply is a module (box) separate from the rest of the unit so its heat does not affect the computer.

direct current
The process in which electric current is produced when a spinning shaft rotates magnets inside a generator is referred to as 'Direct Current'. It is not expected to work by the normal standard physics model however some people claim it is just.
There is no liquid inside a plasma television. The "plasma" refers to low pressure gas contained in cells that for the image. When the gas is excited by a voltage across it, it changes state from a gas to a plasma which will pass an electric current. At no time does it become a liquid.

It is quickly dissipated into heat by what-ever minor resistances exist.
Your computer gets it's Direct Current from a power supply which transforms alternating current into DC. They will have a motor inside them,. but's only there to power the fan which ventilates the PSU.
Inside the Electric Circus was created in 1986-07.
A power supply inside a computer is a device, usually a box on a desktop inside the unit which takes in the supplied municipal power (110v to 120v at 60hz for North america and some other countries, and 220-240v at 50hz for many other countries, check!) and changes or steps the voltage down into the needed power rails for a computer which then supplies the 12v, 5v, 3.3v and their negative counterparts in Direct Current (DC) which the computer uses. Most modern electric sources provide AC (alternating current) these days so the PSU (Power supply unit) is needed to convert the voltage, down step it to the needed levels and supply it to components. Most laptops have external PSU (power bricks) which do the same thing by providing a single, DC Rail, ranging all over the place, as low a 9v up to as high as 22.5v depending on the model of laptop. Hope that helps!
