How To Fix PSU Overheating In 2023

How To Fix PSU Overheating

A computer’s power supply unit (PSU) is one of the most important – and often overlooked – components in a system. When a PSU overheating it can cause a variety of problems including reduced system performance, data loss, and even component damage. Fortunately, there are several steps that can be taken to help fix a PSU that is overheating.

Can a bad PSU cause overheating?

In most cases, it is highly unlikely that a bad power supply overheating. A PSU can only generate so much heat before it fails, and this amount is usually not enough to cause a system-wide thermal event.

Additionally, the cooling system in most computers is designed to handle more heat than a PSU can produce. There are some circumstances in which a bad PSU overheating, but these are rare and usually involve heavily overclocked systems or multiple graphics cards. In general, it is safe to assume that a bad PSU will not cause your computer to overheat.

There are a few telltale signs that your power supply overheating, the most obvious one being if your computer is shutting down or restarting unexpectedly. Another sign is if your computer is running slow or making strange noises. If you’re experiencing any of these problems, it’s a good idea to check to see if your power supply is overheating.

The simplest way to determine whether your power supply overheating is to touch it. If it’s PSU hot to the touch, then it’s likely that it’s overworked and needs to be replaced. You can also check the temperature of your power supply by using a program like Speed Fan or HW Monitor. If the temperature is above 50 degrees Celsius then your power supply overheating.

How do i stop my power supply from overheating?

When you are using your computer, and start the power supply overheating, the first thing you should do is open up the case and use external fans to cool it down quickly. If you don’t have any external fans, then you can try to blow on the power supply to help cool it down.

Once the power supply has cooled down, you can close the case and continue using your computer. If the continues to power supply overheating, then you may need to replace it.

Clean the inside of your computer

Computer cleaning is important not just for the health of your machine, but also for the overall performance. Dust and other debris can accumulate over time and cause your computer to run slowly and even overheat. While it’s important to clean the outside of your computer, you must also clean the inside in order to achieve the best results.

There are a few simple steps you can take to clean the inside of your computer.

  • First, unplug your computer and remove all of the cables.
  • Next, remove the screws that hold the case together and carefully open it up.
  • Once you have opened it up, use a vacuum cleaner or a soft brush to remove all of the dust and debris.
  • Make sure to be careful not to damage any of the components while you are cleaning.
  • Finally, reassemble your computer and plug it back in.

Check the airflow configuration inside your computer case

Manufacturers have long known that the PSU should draw air in from outside the case directly. But in more recent years, they have intelligently decided that this should be done instead of drawing air in from inside the case. This is because when the PSU pulls air in from inside the case, it also pulls dust and other particles with it. These can cause problems with the internal workings of the computer and can also lead to overheating.

To check the airflow configuration inside your computer case, you can use a simple tool like a ruler. Just hold it up to where the fans are located and see if there is an even distribution of air coming out of them. If not, you may need to adjust some things to ensure that your computer runs cooler and more efficiently.

Check all connectors are pressed in properly

PSU connectors can easily be disconnected if not properly pressed in. This can cause the PSU overheating as well as other problems. Always check that all connectors are properly connected, and press them in until they are fully seated.

Make sure the PSU fan is working

It s important to keep your computer running cool, especially if you re overclocking it. One way to do that is by making sure the PSU fan is working properly. If it doesn’t spin up or spins up too slowly for the heat being generated, then something is either wrong with the fan itself or with the controller. In either case, you will need to take action to fix the problem.

Make sure the room temperature isn’t too high

Your computer’s power supply is one of the most important components. It’s responsible for providing power to everything else in your PC, so it’s crucial that you choose a quality unit.

One factor to consider when selecting a PSU is the ambient room temperature. If the room is too hot, the PSU will have to work harder to keep your system running, and that can lead to premature failure. So make sure the room temperature isn’t too high before you buy a PSU.

Another thing to look for is reliability. You want a PSU that will last, so be sure to read reviews and check manufacturer warranties before you make your purchase. Finally, don’t forget about price. PSUs come in all shapes and sizes, so there’s one for every budget. Just be sure to buy from a reputable dealer to ensure you’re getting a quality product.

Your computer’s internal temperature is something you should always be aware of, as it can affect your PSU overheating temperature and in turn your system stability. There are a few things you can do to make sure your PC is running at a reasonable temperature.

check the case fan speed profiles and make sure they’re set to the right speeds; ensure that your BIOS is up-to-date; and keep an eye on your CPU and GPU temperatures. If you find that your PC is running too hot, there are a few things you can do to cool it down, such as installing more case fans or replacing the thermal paste on your CPU or GPU.

When all else fails, replace the PSU

When all else fails, replace the PSU. If your computer is still overheating after checking all the fans, thermal paste, and dust build-up, it’s possible that your power supply unit is to blame. PSUs can overheat for a number of reasons, including age, poor ventilation, and excessive load.

If you’ve ruled out all other potential causes and your PSU overheating try contacting the manufacturer for a return or replacement. Spending a little money on a new PSU can save you from having to replace your entire computer.


An overheating power supply unit (PSU) is one of the most common problems that can occur in a computer. In this article, we have given you the top reasons for an PSU overheating. We hope it has given you the information you need to get it fixed.


Is it okay for PSU to get hot?

If the power supply box is too hot to touch, it has overheated. Overloading can cause power supplies to overheat and possibly lead to component damage. Fan failure.

Can you water cool a PSU?

It’s possible. You can even get it with RGB lights! With the Hydro PTM+ 1200W PSU, the first mass-produced, liquid-cooled platinum-rated PSU, the PSU industry has made a bold move forward.

Can a PSU fry a motherboard?

Most motherboards and power supply units adjust their voltages to handle small surges of power. But if the surge is large, it can damage your motherboard and all components. This is a serious issue that we don’t always account for properly.
