Electrical Considerations

2.5.1

DC Loading

Table 21 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.
