When any part of your computer fails, it can be very frustrating. This frustration is maximized when you receive the bill for the needed services from the repair shop. The power supply is a computer component that commonly fails. You will find that self repair of the computer will save money over repair shops in most cases. The following guide will outline the basics of detecting and replacing a faulty power supply.
The power supply, also know as the PSU, does just what its name implies. It supplies power to the computer’s components through a series of connectors and wiring. When the PSU begins to fail, a user might experience freezing, crashes, and the infamous Windows blue error screen. When the PSU is completely dead, your computer will not start. It is best to catch the symptoms of power supply failure early but sometimes the symptoms may not be due to a faulty PSU. If you are experiencing a failing PSU, you will need to test the PSU to confirm your suspicions.
If you do not already have one, you will need to purchase a power supply tester. PSU testers are readily available online and are relatively cheap. Read the instructions that were included with your tester carefully. Make sure to follow all of the safety precautions since you are working with a potentially dangerous component. The process of testing the PSU will usually take about 30 minutes and results will vary based on the tester that you use. If your PSU fails the test, you should replace it. Do not try to repair the unit as this is advised for certified technicians only.
The first step in replacing your power supply is determining how much power you will need for your new supply. Often times, wattage equal to that of the old PSU is sufficient. The wattage can usually be found on the side of the unit. If you are unsure if a specific unit is compatible with your machine, consult a professional. PSU replacement usually takes less than 15 minutes and your computer will be as good as new when all is said and done.
