2.5 Electrical Considerations
2.5.1 Power Supply Considerations
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 be used in systems that have 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.
2.5.2 Fan Header Current Capability
Table 29 lists the current capability of the fan header.
Table 29. Fan Header Current Capability
Fan Header Maximum Available Current
Chassis fan 1.0 A
2.5.3 Add-in Board Considerations
The board is designed to provide 2 A (average) of +5 V current for the PCI
Conventional slot. The total +5 V current draw for the PCI Conventional expansion
slot (total load) must not exceed 2 A.
