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).
