Computer power supply troubleshooting.

Steps for diagnosing a computer power supply

Troubleshooting Power Supply

• The process of identifying the power unit as the source of a computer system's issue is known as computer power supply troubleshooting. One of the key components of a computer system is the power unit, which is in charge of providing the necessary electricity to every component of the PC system.
• The power supply changes the 120V or 240V AC wall electricity into various DC powers. Among these voltages are 12, 5, and 3.3 volts. This is because not every component of a computer requires the same amount of electricity.
• As an illustration, chipsets, PCI cards, and memory chips utilize +3.3V while disc drive motors and fans use 12V.

The causes of a computer power supply issue

There are numerous potential causes for power unit malfunction, but the following ones continue to rank highest:-

• Electricity fluctuation or power overload.
• Replacing fan that demands more power than the power supply can provide
• The power unit fan's deterioration.
• Old power supply.

How do you recognize a faulty PC power supply?

• The power button should be pressed if your computer is dead or won't start.
• Unwanted system shutdown or restart.
• Hard disc platters consistently spin.
• Overheated power unit
• Burned circuit board components.

Some important steps for troubleshooting a computer power supply.

• To avoid burning the power unit, make sure your country wall electric power sources are 120 V or 240 V so you may change your power unit to the appropriate switch. On my machine, this occurred.
• Ensure that the poor power cord and wall power are the cause of the power supply issue.
• Make that the motherboard, hard drive, and other components are properly seated in the power cable.
• By connecting each component individually, identify the component that caused the power loss. The last resort is to replace the power supply if it cannot be fixed.

Note:- Make sure the form factor, input/output power, physical size, shape, fan direction, and screw hole placements are equivalent to the old power unit, though, before going out to get a new one.

Step to protect power supply from failure.

• The first step in preventing power unit failure is to turn off and unplug your computer equipment after using it. 
• Additionally, there are devices created to safeguard computer components against power-related issues, such as surge protectors and UPSs (Uninterruptible Power Source).
