Computer Power Supply AT and ATX

Computer Power Supply is a duty to provide power to every other computer devices. fleeting presence of power supply in a PC is just an additional component, seen so much discussion in cyberspace about the power supply is still very small, but if you look overall at the computer system, the power supply is a crucial component in the continuity of the work PC, because obviously, without the power supply is working properly will affect the performance of other computer hardware. Power supply is also a device that is used to change the flow of electricity from the AC (alternating current) to DC (Direct Current), because each component of computer hardware can only accept DC electric current (are unidirectional).

Power supply cable fitted with a DC current with a wide - range of connector types that my goal to facilitate the distribution of the current in each component of computer hardware, plug flow owned, among others:

Connector 20/24 pin ATX Motherboard (provide main power to the motherboard) 4-pin peripheral power connector (supply power to the type of IDE hard drive, CD-ROM, and sometimes for an additional FAN / Fan) Connector 4/8 pin 12V (supply power to the motherboard server) 6-pin PCIe connector (drain current types of PCIe graphics card) Floppy connector (supply power floppydisk drive) SATA connector (provides power to Disk and CD-Room type SATA)

For this type of power supply itself there are 2 that AT and ATX:

Power Supply type AT (Advanced Technology)
Is a power supply that has a power cord that plugs into the motherboard separated into two power connectors (P8 and P9). Power Supply characteristic of this type is now shut down the computer, it is not enough just to run the system shutdown, but we have to press the power button after system shutdown running. Power supply is used up in the era of computer pentium 2

Power Supply type ATX (Advanced Technology Extended)
Is a power supply that uses a 20/24 pin main power cable to the motherboard. This type of technology is the latest power supply current. where the system will automatically stop the computer used only by system shutdown without having to press the Power button to turn off his
