Please continue reading to discover potential reasons for the Power supply making a clicking noise and how to resolve them. Your power supply will alert you if one of its connections is bad by automatically generating clicking noises or shutting down. If there is a voltage mismatch, it shuts off power to prevent additional damage to the components.

Power supply making a clicking noise 1

It can be terrifying to hear clicking sounds coming from your computer suddenly. In this instance, you ought to begin by inspecting the power supply unit. There are several potential offenders for the noise, and all of them are connected to the PSU. Even while the issue may be something straightforward and easily resolved, you should still treat it seriously and address it immediately.

Power supply making clicking noise:

Instead of just generating noise when you use your computer, your power supply typically makes an odd noise when it initially turns on. There are various causes for your power supply to click, and you should look into all of its components, including the fan.

You should be aware that most power supplies create a ticking sound the first time they are turned on and off, usually just once or twice. If the clicking keeps happening, you have a bigger issue on your hands. But if the clicking sound from your power source persists, you should look into it. It would help if you didn’t disregard this.

Solution for Power supply making a clicking noise:

Failing PSU:

You may face a “Death Knell” if you have attempted the above remedies without a positive outcome. That’s a term used in extreme situations when a power supply warns you by making clicking noises that it may soon fail. Sadly, there is no method to undo it and make changes. The sooner you acknowledge that the PSU needs to be changed and is broken, the better.

Failing PSU

A crucial component of a computer, the power supply ensures the security and functionality of all other computer parts. Look for PSUs from reputable and well-known manufacturers. Avoid trying to save costs on this component. To locate and pick the best PSU, you must first determine how much power each component of your PC consumes, add those numbers together, and then buy a PSU that can easily supply them all.

Fluctuating Voltage Regulator:

Voltage regulators are built into every power supply to track incoming voltage. Its function shields other components, including the PSU, from common voltage fluctuations. The electricity can occasionally go out and then come back on quickly.

Voltage spikes can also occur. Both scenarios can potentially destroy the other PC parts and the power supply. You’ll hear a clicking sound as the voltage regulator repeatedly turns the PSU on and off to safeguard it.

Another explanation is that the PSU is experiencing spikes. Please turn off your computer and leave it off while you wait for the power to stabilize.

Faulty Power Supply Fan or Filter:

Sometimes the PSU’s fan is the source of the clicking noise instead of the PSU itself. If the fan is either broken or dusty, it may begin to click. It must be replaced if the fan is broken or damaged.

You’ll need to clean it with compressed air and brushes if it has become blocked over time from the accumulation of dust and dirt. To stop the clicking issue from recurring, do this sometimes. A few PSUs also contain filters that capture dust and other pollutants.

Faulty Power Supply Fan or Filter

After a while, if these filters become clogged, the power supply may overheat, work harder, and click. Remember to also clean the filters.

Overclocking or Over-Usage Issues:

Overusing a computer means putting excessive demands on its parts. For instance, your PC might become overloaded if you are concurrently playing a game, listening to music, and having many open tabs. The power supply will become worn out, the fans will run more frequently, and the components will overheat.

The power supply will struggle to keep up if you attach too many peripherals to your computer, such as additional fans, RGB lighting, and so on, and it will eventually click.

Additionally, if you don’t take the proper precautions, overclocking, and pushing your hardware to its limit, might have additional detrimental effects on your system. The parts of your computer should be able to be overclocked. If you intend to overclock, you should install additional cooling systems.

Make sure the PSU can handle the additional power the PC will be consuming by considering that. If your PC is overworked or overclocked and you hear a clicking sound, gradually return your system to its default settings.

Don’t subject your PC to those high demands once the clicking sounds cease. If not, some of the parts may have suffered irreparable damage. Make a complete inspection.

Loose Cables:

Due to deterioration or an outside action, some of the wires inside the enclosure may have come loose. That might be a problem, particularly if you constructed your PC and didn’t secure the wires properly.

The clicking sound could have been brought on by a hanging wire being knocked against the other components by the wind from the fan. It might also be in communication with a fan. Open the computer, disconnect the power cord, and reattach any loose wires.

Improper Installation:

The clicking noise is one of several problems that might arise from improper PSU installation. If you build your computer, it’s possible that you installed the power supply incorrectly or backwards. If your PC was constructed by someone else, this problem might still exist, so check it out by opening the case.

To determine the proper installation procedure, consult the case manually. Don’t disregard this issue because a poor installation could result in the PSU malfunctioning or, worse, catching fire. Additionally, ensure all the PSU mounting screws are well attached. The PSU may rattle and create a clicking sound if they are loose or missing. Look around the interior of the casing for any missing screws.

Faulty Connections:

Since the PSU supplies power to all of the internal components, you must ensure that each one is securely connected and that the cables are linked to both the PSU and the relevant element. There is a 24-pin power cable on the motherboard. For individual feeding of the CPU, another eight-pin connection is used.

These days’ GPUs require separate power lines. It is a PCIe connector with six or eight pins. A SATA power line connects the PSU to the storage disks.

SATA power cables are also used by other equipment like optical drives and CPU liquid coolers. Open the case of your computer after detaching it from the electrical outlet. Verify that every connection is made and plugged in properly on both ends.

To Conclude:

The duration and regularity of the clicking sound are critical factors in figuring out the Power supply making clicking noise. Many power supply systems commonly create a ticking sound during startup or even shut down your PC. There is no need for concern if the clicking only occurs a few times before ceasing. You have a problem if the clicking sound persists or sometimes appears.

Additionally, suppose your computer makes loud clicking noise before shutting down unexpectedly. In that case, your power supply or wiring may malfunction because the sound is caused by all of the components pausing due to a power outage.

If your power supply fails, it could cause serious or perhaps irreparable harm to your entire computer. Back up all of your files immediately and start looking into the strange sounds from your computer.

Relevant Questions:

Why is my power supply making a weird noise?

There is a significant likelihood that the fan bearing has worn out if the loud/buzzing noises continue without any indication of obstruction. Older and less expensive PSUs used fans with sleeve-bearing fans, which are infamous for creating loud noises as they approach the end of their useful lives.

Why does my PC make a clicking noise when I turn it on?

Your computer has many fans to dissipate heat internally, including fans above the processor, on the graphics card, and even one or two fans to push hot air out the back of the machine. This type of clicking may be brought by a broken fan blade or a clogged fan that can’t turn properly.

Should the power supply be making noise?

As quickly as the PSU starts to produce noise, check the fan blades to ensure they are free of any obstructions or dust accumulation on the edges. The fan won’t function properly with either of the two. The volume is due to this.

Why is my PC clicking and not turning on?

This might be brought on by a defective PSU or another system component shorting out and shutting down the PSU. 2. To perform standard debugging, all USB devices, video cards, and RAM must be removed, and all cables must be disconnected except for the CPU fan, 4/8-pin and 24-pin MB power connectors, and the motherboard.
