Power Supply

A computer other than the main component of Motherboard, Processor, Memory, and others, they all need a Power supply. Power Supply is also an important component to a computer. A power supply has several connectors for power distribution to antaralain computer components to the motherboard, CD / DVD room, HDD etc..

Power supply has developed, adapted to the development of the motherboard and processor. There are several types of power supply among others:

Power To Motherboard

1. Power Supply AT
Has a 12 pin connector, this connector is used for older computers are pentium 2 down. There are two power cables to the motherboard consists of 6 pins. Mining section called Power 8 (P8) and the second part is called Power 9 (P9). With mounting between P8 and P9 when in Align the black cable in the midst. Apart from the power cable to the motherboard is also included with the cable and molex connector Berg

2. 20 Pin ATX power supply
Power supply is used for computer pentium 2 and pentium 3, in which power is distributed to the motherboard using a connector ATX 20 pin connector and coupled with a connector for the floppy disk connectors (Berg) and connectors for hard drives, DVDs etc. (Molex connector) which has 2 voltage is 12 volts and 5 volts.

3. Poser Supply ATX 20 +4 Pin
Development of the motherboard and processor, as used in the Pentium 4 and above, the number of pin power connector to the motherboard there are two connectors with 20 pins and 4 pins and also comes with several connectors Molex and Berg.

Now let us explain one by one cable connector at the power supply apart from the power for the motherboard.

1. Berg Connector: This connector is a small, used of power floppy disk, this is usually used for older computers are Pentium 4 down, today many power supply already negate this berg connector for floppy disks are not used anymore replaced with flash disk. On this connector there is a voltage of 12 V (black (-) and Yellow (+)) and 5 volts (black (-) and red (+))

2. Molex connector, this connector consists of 4 pins with a voltage of 12 volts (black (-) and Yellow (+)) and 5 volts (black (-) and red (+)), used as a power to the hard drive, CD / DVD Room.

3. Sata Power Connector, The evolving technology where computer equipment has been using sata, then over time the Molex connectors are no longer held in the power supply, sata connector is also used as a power for the HDD and CD / DVD. Bisasanya for the power supply still uses Molex connectors to connect the Molex connector to the sata cable.

4. Connector Pin Intel 12 v 4
This connector is used as a power supply to the motherboard using an Intel Pentium processor, and some AMD processors. Starting from sebahagian Intel pentium 4 and pentium dual core and above, its function as a provider of an additional voltage of 12 volts to the processor.

5. Connector 6 pin PCI-E connector is rarely found on the PC. Usually this power supply berfungis to add power to the PCI-E graphics card, which will be used to process Grafick work, video editing, and 3d Game. Power supply not all have this connector, only a special power supply 6 pin PCI-E can be purchased in the market, and if the PCI-E VGA card you have a socket for power.
