Tips for cleaning a power supply inside

Even if you have dust filters in the area of ​​the power supply, the dust ends up entering inside. And as you know, when the powder solidifies because of the heat becomes soot, which can end up causing real disasters since it is a conductor of electricity. For this reason it is essential to also give some maintenance to the power supply and clean it even inside.

Previous steps and necessary material

The previous step is obvious: you have to unplug the power, disconnect from the PC, and disassemble the power supply. Further, it is important to wait about 15 minutes for safety, so that its capacitors discharge completely of energy, before opening it to clean it inside. As a precaution it is also advisable to turn off the source of the button that most incorporate in the back.

As materials, we will need the following:

• A microfiber cloth.
• A clean brush
• A spray of compressed air.

How to clean the power supply inside

The first step is to remove the outer metal casing from the power supply, which is normally anchored with only four screws. Once the casing is removed, it is essential disassemble the fan (normally it is connected to the other part of the interior of the source with a single connector) also to be able to clean it individually (here you have a tutorial to clean fans), as well as the grid behind which it is mounted, inside and out , with the microfiber cloth.

Now we must focus on the interior, where all the electrical components are. The recommendation is start with the brush, making soft passes where there is more concentrated dirt. With this we will remove most of the dust and soot. You do not need to rub or make repeated passes, with passing it gently to remove most of the dirt will be enough.

Once this is done, it is time to start using the compressed air sprayat one distance not less than 10 centimeters and never pointing directly to where there are welded wires. This is very important because if you bring the jet of compressed air too close you could cause something to come loose.

Apply compressed air in areas that you could not access with the brush. Is about remove dirt from small cornersso do it with small keystrokes so that the jet goes out in small bursts, and thus make the dirt come out efficiently.

The source is not going to be totally perfect like that, but you should have been able to clean more than 90% of the dirt. A final step would be to pass the microfiber cloth, completely dry, through the metal walls of both the inside of the fountain and the housing you removed at the beginning. It would only be to reassemble everything and work.

Cleaning the PC power supply is very important, and you should do it at least once a year, or at least every 18 months.
