Power Connectors

The 24-pin ATX power connector
header (JPW1) provides power to
the motherboard. The 12V DC power
connector (JPV1) provides alternative
power for a special enclosure when
the 24-pin ATX power is not in use.
The 4-pin power connector (JPH1)
provides power to onboard HDD
devices.
Note: Do not use the 8-pin DC power
at JPV1 when the 24-pin ATX Power
at JPW1 is connected to the power
supply. Do not plug in both JPV1 and
JPW1 at the same time.
