Checking the power supply of a computer is a crucial step in troubleshooting any hardware issues. A faulty power supply can cause a variety of problems, from random system crashes to complete system failure. By checking the power supply, you can quickly and easily determine if it is the source of your computer’s problems.
There are two main ways to check the power supply of a computer: using a multimeter or using a power supply tester. Using a multimeter is the more accurate method, but it requires some basic electrical knowledge. Using a power supply tester is easier, but it is not as accurate as using a multimeter.
