Why Does My PSU Make Noise?

If you’re asking yourself, “Why does my PSU make noise?” it might be because it’s not seated properly. You’ve probably overclocked it or repositioned the fan, or the coil might be whining. Whatever the case, you need to investigate the cause of this problem. Below, we’ll examine several causes and solutions for this problem. Keep reading to find out the solution to your PC noise problem.

Power supply fan

A noisy power supply fan may be a sign that your computer is overtaxed. If your computer is too hot or overloaded, the fan may start to work overtime and cause the power supply to struggle. Here are some possible causes of a noisy power supply and how to fix them. Check the air filter or fan for debris. If both components are clogged, clean them using compressed air and try again. If neither of those solutions work, try cleaning the power supply fan.

In older, cheaper power supplies, the fan might be made of sleeve bearings. These bearings can wear out and produce noise as they reach the end of their life. You can either grease them or replace them if the noise continues. However, we do not recommend dismantling your power supply just to replace the fan. It will likely ruin your computer’s power supply. If you notice this, you should take it to a repair shop for a professional evaluation.

Another common cause of a noisy power supply fan is an overloaded CPU. Another common cause is a blocked air intake vent. This prevents cool, fresh air from reaching the CPU and the fan. If the air intake vents are blocked, hot air may escape from the power supply. You should remove any obstructions that may be blocking them. Afterwards, try using your computer in a quieter location.

You should also check the temperatures of your CPU and GPU. If they are higher than normal, the power supply may need a replacement. A noisy power supply can also cause your computer to overheat, and the fan may be making noise as it struggles to dissipate the heat. If you suspect that your power supply is the cause of the noise, you should take it to a repair shop for a replacement.

Coil whine

If you’re having problems with coil whine, you probably have coils on your GPU or power supply. However, coil whine can occur in all kinds of hardware, not just your graphics card. If you have a coil whine on your PSU, there are a few things you can do to fix it. First, determine the cause of the whine. It may be caused by the power supply, GPU, or motherboard. If you find that the whine is only heard when the GPU or power supply is overloaded, it is possible to swap them. However, if you don’t have spare parts, swapping out the power supply is the only viable option.

One way to reduce the whine from your PSU is to insulate the PC case. You can purchase PC-specific insulation materials or purchase a bitumen mat to cover the case walls. Just make sure you connect it firmly to the case walls during installation. Otherwise, the coil whine will likely leak out through the vents. However, it is impossible to completely eliminate coil whine, so try to find a way to minimize it.

A high-pitched noise will be the first symptom of a coil whine. It is usually harmless for typical computers and does not indicate a serious problem. If the coil whine is accompanied by a whistling sound, you may want to try using a pair of headphones to block out the noise. In any case, you don’t want to deal with the whine. However, you can take preventive measures to keep it from occurring again.


If your power supply is making noise when you’re overclocking, it is probably because you are pushing it too far. Before you push your power supply to extremes, make sure you have additional cooling systems installed in your PC. Lastly, remember that overclocking is not a good practice, and you could end up damaging your system. If this happens, you should turn your system back to its standard settings slowly.

In addition to overclocking your processor, you can also try repositioning your PSU. If you’re repositioning the power supply, you can make sure that it’s secure by screwing it down firmly. You should avoid touching the parts, as you don’t want to scratch them. If you still hear buzzing noises, you should try undoing the overclock. If the problem continues, check to see if there are any other signs of damage.

Another common cause of power supply buzzing is a conflict between other components. This may happen if wires are touching or brushing against each other. A good way to determine if this is the case is to use a voltage monitor. You should place this on a second screen so that you can monitor it even when you’re not using the computer. This way, you can determine the exact source of the buzzing.

There are several common causes of noise when overclocking a PC. The fan on the power supply unit can make noise when it reaches its sweet spot. If the psu has a 950-watt capacity, it can’t be as efficient as it could be if it were only supplying 950-watts. The resulting heat causes the PSU to run more, which forces its cooling fan to work overtime and increases the noise.

Tightening mounting screws

There are several common reasons why the power supply may make noise when tightening mounting screws. A loose screw can affect the flow of air and lead to reduced performance and even fire. Tightening the screws may help to prevent these problems. To test if the problem has been fixed, you can gently turn the power supply to check if it makes any noise when tightening mounting screws.

Loose or dangling wires can also cause the power supply to make noise when tightening mounting screws. Loose wires can get blown around by the fan or other external movement and hit against other moving components. Identifying and repairing loose or dangling wires can solve this problem. After you’ve ruled out these problems, you can go ahead and tighten the mounting screws.

Fan failure

If you notice that your power supply is making a clicking noise, it’s possible that a fan is failing. Oftentimes, these noises are caused by other components inside your PC. If you’ve noticed a clicking sound, it’s probably a fan, so check that it has multiple fans. If not, try to replace the unit. You can clean the fan with compressed air. If you’ve tried that, you might be able to prevent the noise.

Similarly, if the noise is coming from the power supply, look for components rubbing against it. Cables, sheets, and peeled labels can cause the fan to become overworked. Another possible cause of a loud PSU is an overworked CPU. Also, the case may be obstructed, blocking air intake vents. Cool air should flow in through these vents to avoid hot air from accumulating inside the computer.

The problem is usually not immediately apparent, but you can test if the noise is coming from your PSU by listening to it. You can check the components by removing and repositioning them. You should also check the drive motors if they’re making noises. If this fails to solve the problem, you should replace the PSU as soon as possible. If you have an old PSU, you can use it as a temporary spare or for testing fan motors and drives.

Another cause of a loud PSU is a dirty fan blade. It’s possible that a dust or obstacle has collected on the fan’s blades, which impedes its ability to function properly. Using your computer in a desk where cool air can circulate will help reduce the noise. If you’re unable to do either of these things, the problem is likely a fan failure.
