Setting up the power supply
To install the new power supply:
1Turn off your computer.
2Unplug the power cord from your computer.
3Open your computer case. For instructions, see your computer’s user guide.
4Disconnect power supply cables from the system board and peripheral devices, such as hard drives, optical drives, and fans. Make sure that you note where all the power connectors are because you will need to reconnect the power supply cables.
5Remove the old power supply. For instructions, see your computer’s user guide.
6Install the new power supply and secure it to the computer case with the appropriate screws.
7Reconnect all power supply cables using the notes you made in step 4. Make sure that each connection is secure.
8Close the computer case.
9Plug the power cord into your computer, then turn your computer on.
Troubleshooting
If your new power supply is not working correctly, try the following:
•Make sure that the computer power cord is firmly plugged into the power cord connector on your computer.
•If you are using a surge protector, make sure that it is plugged in and turned on.
•Make sure that the wall outlet is supplying power. For example, plug a lamp into the outlet and turn it on.
•Make sure that the red voltage switch (located on the back of the power supply) is set to the correct voltage setting. The setting for the United States is 115 V. The setting for Europe and other countries is 230 V.
•Make sure that the system board power supply cable is securely connected to the system board connector (24 pin or 20 pin).
•Make sure that all power supply cables to peripheral devices, such as hard drives, optical drives, and fans, are securely connected.
