Make sure the computer power cable is firmly plugged into the power cord
connector on your power supply. This power cable will extend out the back of
your computer.
If you are using a surge protector, make sure that it is plugged in and turned on.
Make sure all cables are firmly connected. 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 to operate incorrectly.
Make sure the wall outlet is supplying power. For example, plug a lamp into the
outlet and turn it on.
Make sure the power switch (I/O) on the back of the power supply is set to ON
(I).
Make sure the 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 motherboard (24 pin or 20 pin).
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.
