Fan Connector Current Capability; Power Supply Considerations - Intel DESKTOP BOARD D955XBK Manual

Intel Desktop Board D955XBK Technical Product Specification

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 36 lists the current capability of the fan connectors.

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 35 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 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 4.2.1.2)
•
All timing parameters (Section 4.2.1.3)
•
All voltage tolerances (Section 4.2.2)
