Installing the power supply
Preparing your power supply:
1Make sure your motherboard, graphics card,
and other components are compatible with this
power supply. Refer to the documentation that
came with each component.
2Check 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.
3For 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.
