2. Turn off your computer. Make sure your computer is turned completely off and is unplugged before you begin taking it apart.

The power supply is the large metal box mounted in your computer where you AC power cord plugs into. The wattage for your new power source should either equal or exceed the original power source wattage.

One by one, carefully remove each connector from the old power supply and attach it to the same location on the new power supply. Once everything is secured you can screw the cover back onto the case.

7. Test out your new power supply. When everything is back in place you can try plugging your AC power cord into a nearby outlet. Turn on your computer and you should be ready to go! Remember to back up any valuable files so that you don’t lose them if another emergency pops up.
