2-5 Mounting the Motherboard in the Chassis
All the motherboards have standard mounting holes to fit different types of
chassis. Chassis may come with a variety of mounting fasteners, made of
metal or plastic. Although a chassis may have both metal and plastic fas-
teners, metal fasteners are the most highly recommended because they
ground the system board to the chassis. Therefore, use as many metal
fasteners as possible for better grounding.
2-6 Connecting Cables
Power Supply Connector
After you have securely mounted
the motherboard to the chassis,
you are ready to connect the
cables. Attach power supply
cables to J32 for an ATX power
supply. See Table 2-2 for pin defi-
nitions of an ATX power supply.

Secondary Power Connector
The Secondary Power Connector
is recommended when a heavy
load of peripherals have been
connected to the motherboard.
Note: Be sure to use a 1 X 6 pin connector and
check the power supply layout before attach-
