Technical Reference 2.10.3 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 30 lists the current capability of the fan connectors. Table 30. Fan Connector Current Capability Fan Connector Processor fan Front chassis fan Rear chassis fan Maximum Available Current 3.0 A 1.5 A 1.5 A 2.10.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 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. System integrators should refer to the power usage values listed in Table 29 when selecting a power supply for use with the board. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the recommendations found in the BTX Interface Specification. 67

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 30 lists the current capability of the fan connectors.

Power Supply Considerations
CAUTION
The +5 V standby line for the power supply must be capable of providing adequate +5 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.
System integrators should refer to the power usage values listed in Table 29 when selecting a power
supply for use with the board.
Additional power required will depend on configurations chosen by
the integrator.
The power supply must comply with the recommendations found in the
BTX Interface
Specification
