Electrical Considerations

2.5.1

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.

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

For example, for a system consisting of a supported 130 W processor (see section 1.4

on page 14 for a list of supported processors), 1 GB DDR3 RAM, one high end video

card, one hard disk drive, one optical drive, and all board peripherals enabled, the

minimum recommended power supply is 460 W. Table 24 lists the recommended

power supply current values.
