Installing the Motherboard
This manual does not cover CPU, RAM, or expansion card installation.
Please consult the motherboard manual for specific mounting instructions and
troubleshooting.
1. Lay the case down with the open side facing up. The drive cages and power
supply should be visible.
2. Make sure you have the correct I/O panel for the motherboard. If the panel
provided with the case isn’t suitable, please contact the motherboard
manufacturer for the correct I/O panel.
3. Line up the motherboard with the standoff holes, and remember which holes
are lined up. Not all motherboards will match with all the provided holes; this
is normal and won’t affect functionality.
4. Remove the motherboard.
5. Screw the brass standoffs into the threaded holes that line up with the
motherboard. Note: Do not over-tighten the standoffs. Some standoffs may
be pre-installed for your convenience.
6. Place the motherboard on the brass standoffs.
7. Screw in the motherboard to the standoffs with the provided Philips-head
screws. The motherboard is now installed.
Connecting the Power and LED
1. Connect the 24-pin Main Power Connector and
the 4-pin +12V connector to your motherboard as
needed. If your motherboard uses a 20-pin connec-
tor, detach the 4-pin attachment on the 24-pin power
connector. (see pictures 1 and 2).
2. Connect the Reset switch (labeled RESET SW) to your motherboard at the
RST connector.
3. Connect the 4-pin molex connector from the front display to a 4-pin molex
connector on the power supply.
4. The Power Switch (labeled POWER SW) connector connects to the PWR connector
on the motherboard.
5. The Hard Drive LED (labeled H.D.D. LED) connector connects to the hard drive
activity header.
Power supply 3-PIN fan signal connector
A three-pin signal connector with blue and black wires is available to connect the
power supply to one of your motherboard’s fan connectors (Note: Some motherboards
have a dedicated fan connector labeled PWR-FAN or PSU-FAN that is specifically for
the power supply). This connector is for monitoring the power supply’s fan speed
only. It is optional—the power supply and its fan will operate normally whether
this cable is connected to your motherboard or not.
The fan speed can be monitored through the BIOS or special monitoring software
that came with your motherboard. To ensure proper monitoring of the power supply
fan, please check your motherboard manual.
Note: At low temperatures, the fan may run as slow as 750 RPM (±10%). At
these speeds, some motherboards may not properly detect the fan speed and may
generate false warnings of fan failure.
