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.
