How To Check PSU Temperature

Generally, a power supply unit (PSU) converts main AC power to low-voltage regulated DC power for a computer’s internal components. 

One of the most common hardware parts to fail in a computer is the power supply.

When you are troubleshooting a lot of issues, testing your computer’s power supply is an essential step, and it is especially useful when your system won’t start.

Using the PC for an extended period of time causes the PSU to become hotter. Therefore, the PSU should be as efficient as possible.

How To Check PSU Temperature

The following are the tips used to monitor or check PSU temperature: 

Computer Will Shut Down

The best feature of our system’s power supply is that it will immediately shut down the system if it detects excessive heat. 

Simply put, all computer systems are designed in such a way that they turn off when the temperature of those components rises above a certain threshold that cannot be monitored with software.

Use A Temperature Monitoring App

Though there is no software that can directly detect PSU heat, some can assist us in measuring CPU temperature, Graphic card temperature, and, of course, hard disc temperature. 

The CPU core temperature is also related to the temperature of the power supply.

Check The Temperature Of Exhausted Air Using A Thermometer

The simplest technique to check the PSU temperature is to open the CPU cabinet and inspect it personally, but you may not always be able to do so. 

In such instances, you may easily bring a thermometer near the exhaust unit to measure the temperature of exhaust air, which will be the same for your system’s PSU.

During Gaming

When you play large and bulky games on your system, it is only natural for your system to experience hangs and temperature increases. 

If your computer’s RAM is not as large as the dedicated RAM limit for playing the game, your system’s PSU is likely to overheat. 

In addition, if you are running multiple applications at the same time, the PSU temperature is still likely to rise due to a lack of available free RAM. 

Hold Your Hand In Front Of The Fan

Every laptop has a CPU fan space on the back portion of the base, which may be found at any location on the back portion of your laptop. 

You can place your hand directly after this spot to see if the system has heated up. To keep your system temperature under control, you can use a CPU cooling pad.

App For Monitoring Motherboards

The temperature of your power supply is also linked, either directly or indirectly, to the temperature of your computer’s motherboard. 

On the internet, there is a program called Motherboard Monitor that can be downloaded and used to monitor PSU temperature by monitoring the motherboard temperature.

Conclusion

How long a PSU can last is vital to determine. PSU failure might result in a slew of issues. For example, a severely damaged power supply would prevent the machine from booting at all.

The power supply cooling fans might fail to provide adequate cooling, causing the CPU temperature to rise to unsafe levels. 

Blue screen of death (BSoD), frequent computer crashes, storage failure, inability to start the software, hard disc reading difficulties, and other minor issues are all typical problems linked with the power supply.

If these issues recur regularly, the power supply should be checked first. If it is faulty, it is better to replace it.
