2.10 Electrical Considerations
2.10.1
DC Loading
Table 29 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.

Add-in Board Considerations
The board is designed to provide 2 A (average) of +5 V current for each add-in board.
The total
+5 V current draw for the board is as follows:
a fully loaded D101GGC board (all three expansion
slots and the PCI Express x16 add-in card connector filled) must not exceed 8 A.
