How to Check PSU Temp?

how to check psu temp


When it comes to identifying PC problems, the power supply is often overlooked, but testing it first might save you a lot of troubleshooting difficulties down the line.

When we use the PC for an extended amount of time, the PSU, or power supply unit, becomes hot. PSU efficiency is essential.

Now, it is a scientific concept that heat energy created within any device simply indicates that half of the energy delivered to the system or appliance is squandered as heat, as it is generated from the same power source that we use to operate the system.

The ideal remedy in such a situation is to turn off the system or install an air circulation or air conditioning system in that region to cool it, but in order to know when the PSU gets hot, we need a functioning technique to monitor the PSU temperature, which you can achieve by reading on.

Check PSU Temp

Use these tips to monitor or check PSU temperature:

Computer Will Shut Down

The finest feature of our system’s power supply unit is that it will immediately shut down the system if it overheats. Simply put, all computer systems are intended to turn off when the temperature of those components rises over a level that can’t be monitored using the software.

Use a Temperature Monitoring App

Although there are no programs that can directly monitor PSU heat, there are certainly plenty that can assist us in measuring CPU temperature, hard disk temperature, and, of course, graphics card temperature.

The temperature of the CPU core is linked to the temperature of the power supply.

Check the Temperature of Exhaust Air Using a Thermometer

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

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

During Gaming

When you play high-end graphics games on your PC, it’s only natural for your system to experience hangs and temperature spikes.

If your computer’s RAM is less than the designated RAM limit for playing the game, your system’s PSU is likely to overheat, and if you’re running numerous apps at the same time, the PSU temperature is still likely to rise due to the lack of free RAM.

Hold Your Hand in front of the Fan

Every computer has room for a CPU fan on the rear section, which may be found at any position on the back portion of your laptop base.

You may verify if the system has heated up by bringing your hand right after this spot. To keep your system temperature under control, you can utilize a CPU cooling pad.

App to Monitor the Motherboard

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

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

Recovering From an Overheated Power Supply

First, check what PSU do you have. Two power supplies are housed in a storage enclosure. A built-in temperature sensor is included in each power supply to protect it from overheating. The fans in the power supply maintain a reasonable operating temperature inside the storage enclosure under typical operation settings, with ambient air temperatures ranging from 10°C to 40°C (50°F to 104°F).

The power supply turns off automatically when the interior temperature reaches 65°C (149°F). If both power sources fail due to overheating, the storage enclosure will be powerless, and all LEDs will be turned off.

Overheating of a power supply can be caused by the following factors:

  • A room with an exceptionally high temperature
  • In the power supply, there was a fan failure
  • Circuitry in the power supply that is defective
  • Vents that are clogged
  • Other devices in the setup or rack fail

The system-error LED and the overtemperature LEDs on the front bezel light up if a fan failure causes overheating. The power supply’s fault LED may also be illuminated. The positions of the LEDs on a storage enclosure may be seen by checking the LEDs.

Remove all rack panels immediately to assist in lowering the rack air temperature and prevent damage to system components when the power sources automatically shut down.

Conclusion

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

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

Blue screens 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 PSU.

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