Answer 2

...It "supplies the power" to whatever device you're referring to.

Baffling, I know.

Another answer:

A power supply converts 120V or 240V AC power (sometimes called "wall", "line" or "mains" power) into various regulated DC voltages needed in a piece of electronic equipment. In a computer, for example, the power supply will typically provide +12V, +5V, +3.3V and -12V sources to the various components. Voltage regulators in the power supply help keep the voltages steady, even when the input voltage sags.

Answer 3

An ATX power supply is a power supply designed for ATX and microATX motherboards. It has a single connector to the motherboard with 20 or 24 pins. Unlike older power supplies, ATX power supplies typically do not have switches. A button connected to the motherboard and placed on the front of the computer tower is deperessed momentarily to signal the supply to activate. The power supply can also be shut off by the motherboard.
