Which multimeter setting should you use to test a computers power supply output?
Want to learn how to test power supply with multimeter? then you are in the right place, A power supply is an important piece of hardware in any computer system. It is responsible for supplying power to all the other components in the system. It is therefore important to test a power supply before you install it in a system, and also periodically thereafter.

There are several reasons to test a power supply. One reason is to ensure that it is providing the correct voltages and amperages to the other components in the system. Another reason is to check for bad capacitors or other defects that could cause the power supply to fail prematurely. Multimeter Basics: What Is A Multimeter, And How To Use ItA multimeter is a basic tool used to measure voltage, current, and resistance. It is composed of a probe to make contact with the object being measured and a digital display. Multimeters are available in analog or digital form. The most common use for a multimeter is to test the condition of a power supply. To test a power supply with a multimeter, set the meter to volts DC. Touch the red probe to the positive (+) terminal of the power supply and touch the black probe to the negative (-) terminal. The meter will display the voltage being supplied by the power supply. To test for current, set the meter to amps DC and touch both probes directly across the terminals of the power supply. The meter will display the amount of current flowing through it. What You Will NeedTesting a power supply unit with a multimeter is a simple process that can be done in just a few minutes. You will need a multimeter and a screwdriver. Disconnect the power supply from all devices and unplug it. The first step is to remove the screws from the back of the power supply unit and remove the cover. Once the cover is removed, you will see the internals of the power supply. Locate the positive and negative terminals and test them with your multimeter. Next, set the multimeter to measure volts. Touch the positive lead of the multimeter to the positive terminal on the power supply and touch the negative lead of the multimeter to the negative terminal on the power supply. The voltage reading should be displayed on the screen of the multimeter. If there are any problems with the power supply, this is where they will be identified. Set your multimeter to DC voltage and measure the voltage output on the power supply’s connector. Measure the current output of the power supply by setting your multimeter to AC current and measuring the current on the connector in the power supply. Compare your measurements to the specifications provided by the manufacturer. If the voltage is out of spec, then your power supply may need to be replaced. More Tests You Can Do With A MultimeterA multimeter is a device that can be used to measure voltage, current, and resistance. It can also be used to test power supplies. In this article, we will show you how to test a power supply with a multimeter. To test a power supply with a multimeter, first, make sure that the power supply is turned off. Then, disconnect the power supply from the motherboard. Next, connect the black lead of the multimeter to the ground connector on the motherboard and connect the red lead of the multimeter to the +12V connector on the motherboard. Turn on the power supply and measure the voltage at the +12V connector. The voltage should be between 11.4 and 12.6 volts. If it is not within this range, then you may need to replace your power supply. ConclusionIn conclusion, testing your power supply with a multimeter is a quick and easy way to ensure that it is functioning properly. If you find that your power supply is not working, you can either try to fix it or replace it. By following the steps in this article, you can test your power supply quickly and easily. Skip to content Testing a power supply manually with a multimeter is one of two ways to test a power supply in a computer. A properly executed PSU test using a multimeter should confirm that the power
supply is in good working order or if it should be replaced. These instructions apply to a standard ATX power supply. Almost all modern consumer power supplies are ATX power supplies.https://imasdk.googleapis.com/js/core/bridge3.419.0_en.html#goog_932586545Volume 90% 1:20
Assuming your power supply tested good or you’ve replaced your power supply with a new one, you can now turn your computer back on and/or continue troubleshooting the problem you’re having. Did your power supply pass your tests but your computer still isn’t turning on properly? There are several reasons a computer won’t start other than a bad power supply. See our How to Troubleshoot a Computer That Won’t Turn On guide for more help. Recent Posts
