An important component of the computer is the Power Supply Unit (PSU). An electric power serves to convert AC current from your wall outlet into DC current home as necessary components of your computer. This device is located at the end of the PC casing and can be seen from the back of the PC because it has a hole on AC power and fan for cooling.
Type of voltage generated by power supply was 3.3 volts. 5 volts and 12 volts. 12 Volt used to run the motor on the fan and disk drive, while the voltage from 3.3 to 5 volts used by digital circuits.
An electric power source provides power to all devices on the PC. This tool is an item that tends to damage. The damage is usually due to excessive load. The system is not well grounded. Voltage is not stable and other causes.
One way to keep the gadget is still functioning properly is to clean it regularly. Remove dust on the gadget fan, or replace the fan if it has been damaged. Dust on the gadget fan can cause the fan not to spin properly. If the fan can cause PC damage damaged because the components become too hot (over heat).
If your electrical power source is damaged, look at the instructions / manual book of your computer.
Some tips you can do if your power device was damaged as follows:
# 1 Turn off your computer, then use a brush to clean the power supply. To get the best result you can use a vacuum cleaner.
# 2 Open your PC box, then disconnect all power connectors are plugged into the motherboard and other components.
# 3 Remove the electric power box than a PC chassis for easy checking electronic circuit.
# 4 Uses a screwdriver to open the device box.
# 5 Cleans the dust on the electronic circuit board, examining the possibility of electronic components in them burned or separated from the circuit.
# 6 If the fan should be replaced, remove the four bolts fan PSU by using a screwdriver and attach the new fan.
# 7 To install the new fan, heat and then melt tin solder on the underside of the circuit.
# 8 Replace the electronic circuitry and the fan into place originally. Measure voltage yellow wire (+12), blue (-12), red (+5), orange (POR) on the black cable. If the voltage parameters have shown a valid number then you can use this device again.
# 9 Plugs the PSU into the PC case and reconnects the power connectors and other components with the gadget.
If you want to replace the power supply, make sure the electricity has been turned off, even if your computer is not active, because this device can save electricity that could harm you.
