Checking your computer’s power supply is a crucial step in diagnosing and resolving hardware issues. A power supply unit (PSU) provides electricity to all the components in your computer, and if it’s not functioning properly, it can cause a range of problems, from random shutdowns to complete system failure.
There are a few different ways to check your power supply. One is to use a multimeter to measure the voltage output of the PSU. Another is to use a power supply tester, which is a small device that plugs into the PSU and displays the voltage, amperage, and wattage output. If you’re not comfortable using a multimeter or a power supply tester, you can also take your computer to a qualified technician who can check the PSU for you.
