How to Check a Power Supply :
1: Testing if it Powers On :Shut down your computer. Once the computer has been shut down, or if it isn’t starting to begin with, flip the switch on the back of the power supply. Unplug the power supply from the outlet.
2: Open your computer case. Disconnect the power supply cables from all of the components inside the case. Follow each cable from the power supply to the component to make sure that everything is properly unplugged.
Make note of where everything was plugged into for when you reassemble the case.
3: Make a paper clip tester. You can use a paper clip to help test your power supply and trick it into thinking that it has been switched on. To do this, straighten a paperclip and then bend it into a “U” shape.
This paperclip will act as the pins that are inserted into the power supply that give it the “Power ON” signal.
4: Find the 20/24 Pin connector that normally attaches to your computer’s motherboard. It is typically the largest connector for the power supply.
5: Find the green pin and a black pin (pins 15 & 16). You will be inserting the ends of the paperclip into the green pin (there should be only one) and a neighboring black pin. Before you do this, double check to make sure that the power supply is completely disconnected from any power outlet, that it is switched off, and that it is not connected to any computer components.
The green pin is typically pin 15 on a pin chart.
6: Insert the paperclip. Once you have placed the paperclip into each of the pins, place the cable somewhere where it won’t be disturbed. Plug the power supply back into the outlet, and flip the switch in the back.
7: Check the fan. Once the power supply is receiving power, you should be able to hear and/or see a fan moving. This will let you know that the power supply is at least working. If the power supply does not turn on at all, double check your pins (after unplugging) and try again. If it still does not turn on, then it is most likely dead.
This test will not tell you if the power supply is functioning as it should, just that it is turning on. You will need to perform the next test to ensure that it is outputting correctly.
