Table 37 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.

The Desktop Board D845GVSR is 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 
D845GVSR (all three expansion slots filled) must not exceed 6 A.
