How to Check a Power Supply on Your PC

Everyone wants their computer to be as efficient as possible, whether for business or for leisure, and your computer’s power supply has a significant impact on how well the computer performs. In the event that you do not have enough power to run all of the components of your computer, you may have system failures and crashes that are catastrophic.

As a result, if you wish to improve your computer — for example, by installing a cutting-edge graphics card that consumes more power but can increase your frames per second — you must first ensure that your computer’s power supply is capable of handling the additional demands.

Unfortunately, testing your power source is not as simple as it appears on the surface of things. You won’t be able to verify it using an app; instead, you’ll need to open the casing of your computer and examine the power supply manually.

How to Check the Power Supply on your PC

You’ll need a Phillips head screwdriver to get started, which you can find here. The No. 2 medium size is most likely to be successful. You should also look for a surface that is flat, dry, and free of dust to work on.

1. Reduce the power to your computer to its bare minimum. You may shut down your computer by pressing “Start,” “Power,” and then “Shut Down.” Unplug the device once it has been turned off.

2. Carefully remove the side panel of the computer, which is a component of the casing. Some cases can be unclipped, however others will need the use of a screwdriver to remove anywhere from two to eight screws, depending on the brand and size of the case.

3. Find the location of the power supply. It will be in close proximity to the connector for the computer’s power cord, which you had previously disconnected.

As soon as you’ve located the power supply, have a look at it to see whether it has any useful information, such as the maximum output, measured in watts, and the efficiency rating.

However, if you are unable to get the specific information you want, you should at least attempt to locate the power supply’s model name, which you may then look for on Google.

FAQS

How do I know if my PC power supply is bad?

When your computer won’t even switch on, this is the most clear symptom that your power supply is bad. In the event that everything else on your computer is not working, if your power supply is still operational, its fan should be spinning and you should see a power LED light up anywhere close to the power supply or on the front of the casing.

How do I test my power supply for problems?

Locate the 20+4P (24-pin) connection on your computer. Using the paperclip, bend one end and place it into the green pin (PS ON) and the other end into either of the black pins to complete the circuit (Ground). Turn on the power supply by flipping the switch on the back of the unit and listening for the internal fan. If you can hear the fan running, this should indicate that the power supply is operational.
