■ Installation
Before proceeding with installation, please read through this manual in its entirety.
Step A: Building a brand new system:
(If you are replacing your existing power supply, please go to step B.)
1. Please make sure the HX620W/HX520W is not connected with an AC
power cord.
2. Follow the directions in your chassis manual and install the HX620W/
HX520W with the screws provided.
3. The main 24-pin power cable attached on the HX620W/HX520W has a
detachable 4-pin mechanism in order to support either a 24-pin or a 20-pin
socket on the motherboard.
a. If your motherboard has a 24-pin socket, you may connect the 24-pin main power
cable from the HX620W/HX520W directly to your motherboard.
b. If your motherboard has a 20-pin socket, you must detach the 4-pin cable from
the 24-pin connector, and then plug the 20-pin cable onto your motherboard
without connecting the 4-pin connector.
4. The HX620W/HX520W has an attached 4-pin +12V and an 8-pin +12V
cable; also know as "P4" and "EPS12V" cable.
a. If your motherboard has a 4-pin +12V socket, connect the 4-pin cable directly to
your motherboard.
b. If your motherboard has an 8-pin socket, connect the 8-pin cable directly to
your motherboard.
Warning: The detachable 4-pin from the 24-pin main connector is not a "P4" or "+12V" connector.
Serious damage can be caused if you use it in place of "P4" or "+12V" connector.
5.The HX620W includes 4 Peripheral cables (3 Peripherals on the HX520W), 2
PCI-Express cables, 2 SATA cables, 1 Y-Adapter for small 4-pin devices and 1
Y-Adapter for fan only.
a. Connect Peripheral cable to hard disk power socket (repeat if necessary).
b. Connect Peripheral cable to CD-ROM/DVD-ROM drive's power socket
(repeat if necessary).
c. Connect SATA cable to SATA Hard drive's power socket (repeat if necessary).
d. Connect PCI-E cable to power socket of your PCI-Express video card if required
(repeat if necessary)
e. For any peripheral requiring a small 4-pin connector, connect the Y-Adapter of the
small 4-pin cable to any of the peripheral cable connector, and then connect
the small 4-pin cable to the device's power socket.
f. For any fan requiring a standard 4-pin connector, connect the Y-Adapter of the fan
cable to any of the peripheral cable connector, and then connect the standard
4-pin socket to the fan cable.
Warning: The Y-Adapter for the fan can be only used on standard fans. Serious damage can result if you use it
on other peripherals. If your fan has a pass-through male standard 4-pin connector, please do not use it on your
peripherals. For thermally-controlled fans, please use standard 4-pin peripheral power connectors.
g. After you have connected all your devices, you may connect the other end of the
cables to the HX620W/HX520W front panel.
h. Please make sure all the cables are tightly connected.
