Connect the 20+4-pin main power
connector to your motherboard. If your
computer has an older motherboard with a
20-pin main power socket, connect only the
20-pin main power connector.
Installing the power supply
Preparing your power supply:
1 Make sure your motherboard, graphics card,
and other components are compatible with this
power supply. Refer to the documentation that
came with each component.
2 Check your local AC voltage (115 VAC for USA,
Canada, Japan, and others, and 230 VAC for
Europe, Southeast, Asia, and others). The
NS-PCW5250/NS-PCW5250-C is only
compatible with 115 VAC.
3 For NS-PCW4050/NS-PCW4050-C only: Make
sure that the red voltage switch (located on the
back of the power supply) is set to the correct
voltage setting.
Caution: Using the incorrect voltage can damage the power supply

Troubleshooting
If your new power supply is not working correctly,
try the following:
Caution: Make sure that all connectors are securely connected.
Incorrect connections could prevent your computer from starting
and could damage some components.
• 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.
5 Close your computer case.
6 Connect the AC power cord to the power
supply, then to a surge protector or wall outlet.
7 Turn on your computer by pressing the power
button on the front of the case.
• If you have the NS-PCW4050/NS-PCW4050-C,
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.
Note: For more information, refer to your computer’s user guide.

• Make sure that the system board power supply
cable is securely connected to the system board
connector (24 pin or 20 pin).
• The power supply may be overloaded. Unplug
any unnecessary components, such as extra
drives, then try again.
• 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.
• If the power supply is very hot, check the case
fans and the power supply fan. Replace any faulty
case fans, then try again.
• If you have the NS-PCW4050/NS-PCW4050-C,
make sure the power switch (I/O) on the back of
the power supply is set to ON (I).
