Add-in Board Considerations
The board 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 board (all three
expansion slots and the PCI Express x16 connector filled) must not exceed 8 A.
2.10.4
Power Supply Considerations
CAUTION
The +5 V standby line from 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 34 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 indicated parameters of the ATX form factor
specification.
