PWR Connectors
The 24-pin main power connector
(JPW1) is used to provide power to
the motherboard. The 8-pin Auxiliary
PWR connector (J41) is also required
for the processors. These power
connectors meet the SSI EPS 12V
specification. See the table on the
right for pin definitions of these con-
nectors.

8-Pin Auxiliary Power Connector

In addition to the ATX main power, the
8-pin 12V power connector located at
J41 is also required to provide power
to the South Bridge, North Bridge and
all VRMs. See the table on the right
for pin definitions.
