Testing a power supply on a desktop computer using a power supply tester device is one of two ways to test one in a computer. This process isn't for a beginner. However, if you're comfortable working on your computer, these steps should take around 30 minutes. Testing a power supply unit involves working around high voltage electricity, which is a potentially dangerous activity.

Do not skip this step. Safety should be your primary concern when working around a power supply. After you read the safety tips, it's time to get started:. Turn off the PC, remove the power cable, and unplug anything else connected to the outside of the computer. Then, open the case.

To make the power supply test easier, move the disconnected and open case somewhere you can easily work with it, such as to a table or other flat, non-static surface. Unplug the power connectors from every internal device inside the computer. An easy way to make sure each power connector is unplugged is to work from the power cable bundle coming from the power supply.

Each group of wires should terminate at one or more power connectors. It's not necessary to remove the actual power supply from the computer, nor should you need to disconnect any data cables or other cables not connected to the power supply.

Group all the power cables and connectors together for easy testing. As you organizing the power cables, pull them away from the computer case as much as possible to make it easy to plug the power connectors into the power supply tester. Check to make sure that the power supply voltage switch located on the power supply is properly set for your country.

In the U. Depending on the PSU that you have, you might not have a 4-pin motherboard connector but instead a 6-pin or 8-pin variety. If you have more than one type, only plug in one at a time along with the pin main power connector. Plug the power supply into a live outlet and flip the switch on the back. Some power supplies don't have a switch on the back. If the PSU you're testing doesn't, plugging in the device is sufficient to provide power. You should hear the fan inside the power supply begin to run.

Some versions of the Coolmax PS tester don't require that you hold down the power button, but others do. Just because the fan is running doesn't mean that your power supply is supplying power to your devices properly.

Also, some power supply fans don't run when being tested even though the PSU is fine. You need to continue testing to confirm anything. Confirm the LCD on the power supply tester is lit, and you see numbers in all the fields.

If any voltage reads "LL" or "HH" or if the LCD screen doesn't light up at all, the power supply isn't working properly; you need to replace it. You're just looking at the LCD screen at this point, so don't worry about any other lights or voltage indicators not located on the actual LCD readout.

Check Power Supply Voltage Tolerances and confirm that the voltages reported by the power supply tester are within approved limits. If any voltage is outside of the range shown, or the PG Delay value isn't — ms, replace the power supply. The tester is designed to give an error when a voltage is out of range, but you should check yourself to be safe.

If all the reported voltages fall within tolerance, you've confirmed that your power supply is working properly. If you'd like to test the individual peripheral power connectors, continue testing. If not, skip to Step Turn off the switch on the back of the power supply and unplug it from the wall.

Don't connect more than one of these peripheral power connectors at a time. You probably won't damage the power supply tester doing so, but you won't be accurately testing the power connectors either. Both of the motherboard power connectors that you connected to the tester earlier should remain plugged in throughout these tests of the other power connectors. Plug in the power supply and then flip on the switch on the back if you have one. If not, replace the power supply.

Repeat this process, beginning with Step 11, testing the voltages for the other power connectors. Only test one at a time, not counting the motherboard power connectors that stay connected to the tester the entire time. When the testing is complete, turn off and unplug the power supply, disconnect the power cables from the power supply tester, and then reconnect the internal devices to power.

A test using a power supply tester isn't a true "load" test—a test of the power supply under more realistic usage conditions.

A manual power supply test using a multimeter , while not a perfect load test, comes closer. There are several reasons a computer won't start other than a malfunctioning power supply.
