Power Connectors
The 24-pin ATX power connector
header (JPW1) is used to provide
power to the motherboard. The 4-pin
connector, J1, is the 12V DC power
connector that provides alternative
power for special enclosures when
the 24-pin ATX power is not used.
The 4-pin HDD power connector
J3 provides power to onboard HDD
devices.
Note: Do not use the 4-pin DC power
at J1 when the 24-pin ATX Power
at JPW1 is connected to the power
supply.
