Maintain Power Supply Unit of Computer

PC Power Supply Unit
One of the most important part of the computer is the Power Supply Unit or PSU. This device acts as responsible of converting, commonly in the Philippines is 220-240 Alternating Current Voltages. It will converted down to low level voltages called Direct Current Voltages of computer. Commonly rated as +12, –12, +5, –5, 3.3 DCV standard use to function the computer systems. Inside of this device it is built with variety of electronic components, such as the electronic circuit board and the exhaust fan serves as the cooler or the blower of the temperature to maintain the normal temperature of the electronic components, such as the transformer, capacitors, and transistors. The common cause of the failure of this device is the dust buildup inside. That will cause failure of the exhaust fan coil, because of the stoppage inside and this is because of the locking of lubricant. And this is the start of the weakness of the electronic parts that sensitive of over heat temperature such as the output capacitors that have only 150 degrees Celsius. If this happen to your computer it will cause to restart randomly and this will cause to corrupt and hang- up of the Operating System’s of the computer. That will cause failure of the HDD in the next days of using of your computer.
PSU Full Of Dust Buildup
To avoid this unpredicted failure that probably cause of the burning also of the exhaust fan coil inside of the PSU, we need to perform a maintenance of the PSU by removing the dust buildup inside and check the rotation of the exhaust fan that will rotate freely counter clock wise. Follow the steps below of this post.

1. Open your system case (CPU).

2. Remove the power supply unit, but before to remove be sure that the power cord is unplug and remove the ATX power connector of the Motherboard.

3. Remove the 4 screws position above side by side or above the PSU.
Clean Exhaust Fan
4. Remove the Exhaust Fan by removing the 4 screws holding the Exhaust fan.
Check Damage caps and remove Dust buildup Inside
5. And Remove also the electronic circuit board.
6. Remove the dust buildup of it using a paint brush.
7. And check any initial burning of the electronic parts.
8. Put a lubricant grease of the exhaust fan by removing the sticker and remove the small rubber cap.
Test PSU Using Paper Clips
9. Then if all function of the PSU is normal, assemble the PSU and test it.
10. Use a paper clip and jumper the green wire and black to power-up the PSU.
11. Use a Multitester to measure the voltage DC output of the PSU.
12. If the voltages is normal and correct as I said above assemble it in the CPU and run and test the computer.

13. And if the computer is running normally, your done now.

That’s it see you in next post. “End”
