2-7 Connector Defi nitions

Power Connectors

A 24-pin main power supply connector(JPW1)
and two 8-pin CPU/Memory PWR connectors
(JPW2/JPW3) on the motherboard. These
power connectors meet the SSI EPS 12V
specifi cation. In addition to the 24-pin ATX
power connector, the 12V 8-pin CPU PWR
connectors at JPW2 and JPW3 must also
be connected to your power supply. See the
table on the right for pin defi nitions.
Warning: To prevent damage to the power
supply or motherboard, please use a power
supply that contains both a 24-pin and 8-pin
power connectors. Be sure to connect these
connectors to the 24-pin (JPW1) and the
three 8-pin (JPW2/JPW3) power connectors
on the motherboard. Failure in doing so
will void the manufacturer warranty on your
power supply and motherboard.
Unit Identifi er Button
This motherboar contains a Unit Identifi er
(UID) button. There is another UID button
located on the control panel. When you
push either UID button, both Rear UID and
Front Panel UID Indicators will illuminate.
Push either button again to turn off both
indicators. These UID indicators provide
easy identifi cation of a system unit that may
be in need of service.

Fan Headers

This motherboard has five fan headers
(Fan1 to Fan6). These 4-pin fans headers
are backward compatible with 3-pin fans.
However, fan speed control is available
for 4-pin fans only. The fan speeds are
controlled by the BIOS. See the table on the
right for pin defi nitions
