COMPUTER POWER SUPPLY : POWER SUPPLY UNIT
COMPUTER POWER SUPPLY
Power supply is the part of computer component that is used to convert alternating current voltage (A.C) into direct current voltage (D.C). The short term for power supply that is mostly shown in mostly of books is named as PSU.
The main functions of power supply in computer system is to convert AC voltage into DC voltage.
At any time if power supply fails the computer must shutdown, without power supply computer can never switched on.
POWER SUPPLY INPUT AND OUTPUT.
Computer power supply receiver input power of 120 voltage and 230 voltage.
Computer power supply give out output power of 3.3 voltage, 5.5 voltage or 12 voltage.
PARTS OF COMPUTER POWER SUPPLY.
Below are common componets of computer power supply.
1. Transformer.
2. Rectifier.
3. I.C voltage regulator.
4. Voltage regulator.
5. Power Plug.
6. Input voltage selector.
7. Power supply Fan.
