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
DX-520WPS is only compatible with 115 VAC.
3 For DX-400WSP 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:
1 Turn off your computer.
2 Unplug the power cord from your computer.
3 Open your computer case. (See the instructions that came with
your computer.)
4 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.
5 Remove the screws that secure your old power supply to your
computer case, then remove it from the case.
Installing your power supply:
1 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.
2 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.
