The effect of power surges on PSU lifespan
Power surges are sudden high voltages that can significantly damage the sensitive components in a computer, including the Power Supply Unit (PSU). Power surges occur unexpectedly, and they are either external or internal. External power surges come from lightning, fallen power cables, and faulty transformers. Internal power surges happen when an appliance in the house like an air conditioner turns on abruptly, causing a momentarily increase in the electric current. A PSU that is subjected to continuous power surges can drastically lower its lifespan, and the following are some reasons why.
- Damage to Capacitors: Power surges primarily compromise the capacitor of the PSU. The capacitors are the components that store electrical charge that is then used to power other parts of the computer, and a power surge melts and heats the capacitor’s dielectric, degrading it over time. Ultimately, the capacitors lose their ability to store electrical charge, leading to PSU failure.
- Overheating: Power surges also cause the PSU to generate more heat than usual, which exceeds the maximum limit and could lead to catastrophic failures, such as exploding capacitors, burned-out circuit boards, and melted cables.
- General Wear and Tear: When a power surge occurs, and the PSU manages to survive without causing immediate damage, the internal strain is evident. It is like a car that has covered several miles; sooner or later, the vehicle breaks down due to general wear and tear of the internal components. Consequently, a PSU that has survived multiple power surges could only last for a few months or even weeks before it requires replacement.
To protect your PSU from external power surges, it is recommended to use a UPS (Uninterruptible Power Supply) or surge protector. A UPS allows the computer to run for a few minutes after a power outage that gives you ample time to save any work on your computer and safely shut it down. On the other hand, a surge protector absorbs excess voltage and dissipates it away from the PSU and other connected devices.
If you frequently experience internal surges due to appliances in your house, it would be best to have an electrician install a dedicated circuit for all your computer equipment. A dedicated circuit is an independent circuit installed only for your computer equipment, and it is excellent at reducing internal power surges.
