Atx power i dont really know :(
...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.
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.
Steps down mains power for use with your computer components. ATX power supply regulates, and distributes power to different hardware parts of computer. These includes hard disk, optical drives, motherboard, external fan, and similar components.
the regular ATX has a 20 pin power connector, while the enhanced ATX power connector has 24 pin power connector.

ATX
Yes. The connectors are the same. microATX is designed to be backwards-compatible with ATX, including interchangeable cases and power supplies.
Most ATX motherboards offer a choice of several similar processors. The manufacturer decides which processors can used by a specific ATX motherboard. ATX is a physical and electrical specification. ATX does not define a specific central processor, so theoretically an ATX motherboard could be created for any type or brand of processor that can function within the specification. Common ATX motherboards use either an Intel processor or an AMD processor.
