ATX Power Connector
The X6DA8-G2 includes a 24-pin
main power supply connector (J1B4)
and a 4-pin CPU PWR connector
(J32). These power connectors meet
the SSI EPS 12V specification. You
can use a 20-pin connector, but con-
necting J3 is also required to ensure
sufficient power. See the table on the
right for pin definitions. For CPU
power, please see the item below.
Processor Power
Connector
In addition to the Primary ATX power
connector (above), the 12v 8-pin pro-
cessor power connector at J1D1
must also be connected to your
power supply. (If an 8-pin cable is
not available, please use two 4-pin
cables.) See the table on the right for
pin definitions.
NMI Button
The non-maskable interrupt button
header is located on pins 19 and 20
of JF1. Refer to the table on the right
for pin definitions.

cated on pins 15 and 16 of JF1. Re-
fer to the table on the right for pin
