Several delicate components in a computer work together to run the entire system. However, with the system so complex, it’s always possible to get some minor setbacks resulting in system failure. Power supply failure is one of the most frustrating issues that most computer users face from time to time.
A power supply failure may cause your computer not to boot up, make a lot of noise, feel warm or even smoke. Random shutdowns and reboots, even when there’s plenty of battery left in your laptop, are a possible sign of power supply failure. Here are five signs that are potential indicators of a power supply failure in your system:
- System Fails to Start
If your system fails to start, there could be several reasons behind it. However, if you’re sure that all the cables connecting the main board to other components are correctly in place, it can be a power issue.
In addition, a power supply unit (PSU) may not output enough power to the components of your system, failing to start. You can replace the power supply unit with a known good one and see if your strategy works fine now.
- Overheating of Power Supply Unit
Another sign of power supply failure is overheating. When the power supply fails, it may increase power consumption, which increases heat levels, leading to potential damage. The rumbling noise from your power supply unit may be heard as a rumbling noise.
If your computer is not turning on or is experiencing system shutdowns most of the time, you may hear this noise. Before buying pre built pcs for you, check its power supply unit thoroughly.
- Power Supply Short Circuit
When a power supply fails, it can cause your system to be unstable and avoid booting up properly. In addition, this sign may trigger a system meltdown of the PC, causing an interruption in workflow or display flickering issues.
Also, if you notice one of the power supply plugs slowly slipping out, this might be a sign that your power supply is failing along with other components in the computer.
- Smoke in the Fan
The rumbling noise from the power supply unit may be heard as a rumbling noise. If your computer is not turning on or is experiencing system shutdowns most of the time, you may listen to this noise. This doesn’t necessarily mean power supply failure. Instead, it can be a common problem related to the regular operation of internal components like hard drives, motherboards, and CPU fans.
- Electric Shocks from the Cabinet on Touching
If you notice any electrical shock or shock that feels like being touched by a live wire, all the signs of power supply failure are possible. This is not a common problem with most computers as they have enough safeguards like surge protectors to prevent this type of failure. However, every so often, a high voltage problem causes malfunctioning electronic devices and other components in-home equipment.
The Bottom Line
Proper and thorough maintenance of your PC may prevent this situation from occurring at all. However, if the system is already showing any of the signs of power supply failure, then immediately get it checked by a technician.
