Technical Reference

2.11.3 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.

2.11.4 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 32 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.

• The potential relation between 3.3 VDC and +5 VDC power rails

• The current capability of the +5 VSB line

• All timing parameters

• All voltage tolerances
