Overclocking can cause clicking noise

If you’re wondering why your power supply is making a clicking noise, you’re probably overclocking your computer. While the process itself is perfectly normal, overclocking your PC can put a strain on your computer, so you should always power down gradually and bring the system back down to normal. The clicking noise can also be caused by other components, such as a dirty fan or broken cable. If you’re not sure what’s causing the noise, you can try cleaning the fan or filter.

Manufacturing defects

If your power supply is making noise, it might be a manufacturing defect. You should contact the manufacturer of your equipment to find out if you can have the problem fixed under warranty. In some cases, a manufacturer will replace the entire power supply if the issue is not covered under warranty. If the problem has already occurred and you haven’t been able to solve it through the manufacturer’s customer support, you can contact them directly for help.

Dirt buildup

If you have noticed that your PC is making noise, it could be the power supply. Dirt buildup will increase the fan’s workload and cause noise. Moreover, extreme PC usage may damage the components. Dirt buildup on the power supply can cause a clicking noise. To fix the noise, clean the fan with compressed air. Also, keep the power supply away from siding or walls. Dirt and dust buildup in the power supply’s case may also be causing the clicking noise.

Fan failure

There are several different causes of this clicking noise, including a malfunctioning fan or power supply unit. These causes are easily fixed, and you can try to find out the source of the clicking sound. You should back up any data and files before attempting any repair work. The clicking noise could also be caused by a faulty connection or a loose wire. If you suspect that the fan is the cause, replace the power supply unit.


The voltage can cause damage to electronic equipment when it is outside of its specification. This type of damage is preventable by protective devices. In addition to noise from the power source, ESD damage is also a result of overvoltage. Static electricity applies a high voltage in a short period of time. To protect electronic equipment from this damage, ESD suppressors are required. Ultra Electronics sells these devices.

PSU fan

There are two ways to minimize the noise that your PSU fan makes. The easiest way is to decrease the voltage to the fan. This is usually done by using a resistor attached to the power wire. The noise level will drop as a result. If this option is not available, you should consult your manufacturer. Listed below are several tips to minimize the noise of your PSU. These tips are not applicable to all PSUs, but they may be beneficial to some systems.

Mesh filters on PC components can collect dust

A computer’s power supply and other components can be susceptible to excessive noise when dust accumulates in the cooling system. The problem is not only the power supply, but also the other hardware components, including heatsinks and fans. Dust reduces the effectiveness of these cooling devices, and can cause catastrophic shorts in the power supply, motherboard, and graphics card. As Benjamin Franklin once said, “Prevention is better than cure.”

Cleaning the PSU

If you suspect that your power supply is making a clicking noise, there are a few things you can try. First, clean out any debris and dust that is on the power supply fan. In some cases, a clogged fan is the culprit. You can use compressed air to clean out these components. After cleaning the fan, place it away from the computer’s siding and walls. If you can’t find the problem, you can try repositioning the computer or purchasing new screws.
