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.
Any loose power cable connections may cause the power supply
operate incorrectly.

• The power supply may be overloaded. Unplug any unnecessary

components, such as extra drives, then try again.

• If the power supply is very hot, check the case fans and the power

supply fan. Replace any faulty case fans, then try again.
