Intel Desktop Board D945GSEJT Product Guide

Power Supply Connectors

The board has the following power supply connectors:

External Power Supply – the board can be powered with a 12 V external power supply though a DC connector on the back panel. The rear 12 VDC jack accepts plugs with an inner diameter (ID) of 2.5 mm and an outer diameter (OD) of

5.5 mm, where the inner contact is 12 V and the shell is GND.

Internal Power Supply – the board can alternatively be powered via an ATX12V 2 x 2 power connector. The signal names for the ATX12V power connector are shown in Table 20

NOTE

Use of an external 12 VDC power supply is preferred.

The recommended power rating is 60 W (12 V/5 A) for general purpose use. Total power consumption will depend on the system configuration selected by the integrator; refer to Intel Desktop Board D945GSEJT Technical Product Specification for further guidance.

CAUTION

The external 12 VDC jack is the primary power input connector of Intel Desktop Board D945GSEJT. However, the Desktop Board also provides an internal 2 x 2 power connector that can used be with a target system that already has an internal power supply.

There is no isolation circuitry between the external 12 VDC jack and the internal 2 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 12 VDC jack is covered if the internal 2 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 desktop board, power supplies, or other hardware.
