Installing the power supply

Preparing your power supply:

Make sure your motherboard, graphics card, and other components are compatible with this power supply. Refer to the documentation that came with each component.
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.
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 and connected equipment and may void your warranty.

Are you replacing a power supply?

Yes, start at “Removing your old power supply” below.
No, go to “Installing your power supply” on pg 2.

Removing your old power supply:

Turn off your computer.
Unplug the power cord from your computer.
Open your computer case. (See the instructions that came with your computer.)
Disconnect your old power supply from all computer components.
Tip: Make sure to note each component and the connector type for when you need to connect them to your new power supply.
Remove the screws that secure your old power supply to your computer case, then remove it from the case.

Installing your power supply:

Position your power supply in the computer case, making sure that the AC power jack and cooling fan are facing out, then secure your power supply using the screws included with your computer case.
Connect all power supply cables. Make sure that each connection is secure.
Tip: If you are replacing an old power supply, reference your notes from when you removed the old power supply to make sure you are connecting all of your components correctly.
a 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. b Connect the 8-pin (4+4) or 4-pin +12 V power connector to your motherboard. c Connect all of the following that apply to your computer:
i The 4-pin peripheral connectors (4) to any computer components with a 4-pin connector, such as an IDE drive or a case fan. ii The floppy drive power connector to the floppy drive. iii The Serial ATA connectors (4) to any computer components that have a Serial ATA connector, such as a CD/DVD/Blu-ray or hard drive. iv The 8-pin PCI-E or 6-pin PCI-E connector to a PCI-E graphic card. Caution: Make sure that all connectors are securely connected.
Incorrect connections could prevent your computer from starting and could damage some components.
Close your computer case.
Connect the AC power cord to the power supply, then to a surge protector or wall outlet.
Turn on your computer by pressing the power button on the front of the case.
Note: For more information, refer to your computer’s user guide.

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.
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.
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 to 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.
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).
