Intel NUC D53427RKE Technical Product Specification 2.6 Electrical Considerations 2.6.1 Power Supply Considerations CAUTION The external 19 V DC jack is the primary power input connector of Intel NUC Board D53427RKE. However, the board also provides an internal 1 x 2 power connector that can be used in custom-developed systems that have a custom internal power supply. The internal 1 x 2 power connector is a Molex 5566-2 header which accepts a Molex 5557-02R connector from the power supply. There is no isolation circuitry between the external 19 V DC jack and the internal 1 x 2 power connector. It is the system integrator's responsibility to ensure no more than one power supply unit is or can be attached to the board at any time and to ensure the external 19 V DC jack is covered if the internal 1 x 2 power connector is to be used. Simultaneous connection of both external and internal power supply units could result in potential damage to the board, power supplies, or other hardware. System power requirements will depend on actual system configurations chosen by the integrator, as well as end user expansion preferences. It is the system integrator's responsibility to ensure an appropriate power budget for the system configuration is properly assessed based on the system-level components chosen. 56

Power Supply Considerations
CAUTION
The external 19 V DC jack is the primary power input connector of Intel NUC Board
D53427RKE. However, the board also provides an internal 1 x 2 power connector that
can be used in custom-developed systems that have a custom internal power supply.
The internal 1 x 2 power connector is a Molex 5566-2 header which accepts a Molex
5557-02R connector from the power supply.
There is no isolation circuitry between the external 19 V DC jack and the internal 1 x 2
power connector.
It is the system integrator’s responsibility to ensure no more than
one power supply unit is or can be attached to the board at any time and to ensure the
external 19 V DC jack is covered if the internal 1 x 2 power connector is to be used.
Simultaneous connection of both external and internal power supply units could result
in potential damage to the board, power supplies, or other hardware.
System power requirements will depend on actual system configurations chosen by the
integrator, as well as end user expansion preferences.
It is the system integrator’s
responsibility to ensure an appropriate power budget for the system configuration is
properly assessed based on the system-level components chosen.
