2.11 Electrical Considerations

2.11.1 DC Loading

Table 30 lists the DC loading characteristics of the board. This data is based on a DC analysis of

all active components within the board that impact its power delivery subsystems. The analysis

does not include PCI add-in cards. Minimum values assume a light load placed on the board that

is similar to an environment with no applications running and no USB current draw. Maximum

values assume a load placed on the board that is similar to a heavy gaming environment with a

500 mA current draw per USB port. These calculations are not based on specific processor values

or memory configurations but are based on the minimum and maximum current draw possible

from the board’s power delivery subsystems to the processor, memory, and USB ports.

Use the datasheets for add-in cards, such as PCI, to determine the overall system power

requirements. The selection of a power supply at the system level is dependent on the system’s

usage model and not necessarily tied to a particular processor speed.

Table 30. DC Loading Characteristics

DC Current at:

Mode DC Power +3.3 V +5 V +12 V -12 V +5 VSB

Minimum loading 190.00 W 5.00 A 11.00 A 9.00 A 0.03 A 0.60 A

Maximum loading 286.00 W 11.00 A 15.00 A 13.00 A 0.10 A 1.38 A

2.11.2 Add-in Board Considerations

The boards are designed to provide 2 A (average) of +5 V current for each add-in board. The total

+5 V current draw for add-in boards for a fully loaded Desktop Board D865PCD (all three

expansion slots and the AGP slot filled) must not exceed 8 A.

2.11.3 Fan Connector Current Capability

CAUTION

The processor fan must be connected to the processor fan connector, not to a chassis fan

connector. Connecting the processor fan to a chassis fan connector may result in onboard

component damage that will halt fan operation.

Table 31 lists the current capability of the fan connectors.

Processor fan 1600 mA

Front chassis fan 600 mA

Rear chassis fan 600 mA
