2.11.4 Fan Power Requirements
Table 50 lists the maximum DC voltage and current requirements for the fans when the board is in
sleep mode or normal operating mode. Power consumption is independent of the operating system
used and other variables.

2.11.5 Power Supply Considerations
CAUTION
The 5 V standby line for the power supply must be capable of providing ad5 V standby
current. Failure to do so can damage the power supply. The total amount of standby current
required depends on the wake devices supported and manufacturing options. Refer to
Section 2.11.3 on page 71 for additional information.
System integrators should refer to the power usage values listed in Table 48 when selecting a
power supply for use with this board. The power supply must comply with the following
recommendations found in the indicated sections of the ATX form factor specification.
•
The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2)
•
The current capability of the +5 VSB line (Section 4.2.2.2)
•
All timing parameters (Section 4.2.2.3)
•
All voltage tolerances (Section 4.2.3)
