V Internal Power Supply Connector; Front Panel Header - Intel D53427RKE Specification

2.2.2.3 Power Supply Connectors
The board has the following power supply connectors:
External Power Supply – the board can be powered through a 19 V DC connector
•
on the back panel. The back panel DC connector is compatible with a 5.5 mm/OD
(outer diameter) and 2.5 mm/ID (inner diameter) plug, where the inner contact is
+19 (±10%) V DC and the shell is GND. The maximum current rating is 10 A.
Internal Power Supply – the board can alternatively be powered via the internal
•
19 V DC 1 x 2 power connector, where pin 1 is GND and pin 2 is +19 (±10%) VDC.
The internal 1 x 2 power connector is a Molex 5566-2 header which accepts a
Molex 5557-02R connector from the power supply.
