How to check if a computer power supply works

The power supply of the computer is the one that distributes the current for the whole system. Sometimes when the computer does not start at all, it may be because it has been damaged, but it may also be due to other factors, such as problems with the motherboard or power cords. To rule out the problem of the source, there is a way to test if it works without the need to have an order. Today we will see how to check if a computer power supply works.
