Checking your PC’s power supply unit (PSU) is a crucial step in diagnosing computer problems and ensuring the longevity of your components. A PSU converts alternating current (AC) from a wall outlet into direct current (DC) that your computer’s components can use. When a PSU fails, it can damage other components in your system, so it’s important to be able to check its health regularly.
There are a few different ways to check your PSU. One way is to use a multimeter to measure the voltage output of the PSU. Another way is to use a PSU tester, which is a device that plugs into the PSU and tests its output. You can also check the PSU by visually inspecting it for any damage, such as bulging capacitors or leaking fluid.
