Why My Power Supply Doesn T Work. Im having a similar issue where my power supply will only supply power when it is connected to the tester. Welcome to the forums.
Most power supply models have a light on back of the unit that glows when its powered on. My computer wasnt connected to a breaker when it shut off. You must troubleshoot your Power Supply if its not working or if your console is experiencing any of these situations.
To test your power supply plug it into your computer and see if the battery light is lighting up.
