2.5 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 95 W processor (see Section 1.4
on page 16 for information on supported processors), 2 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 26 lists the recommended
power supply current values.
Table 26. Recommended Power Supply Current Values
Output Voltage 3.3 V 5 V 12 V1 12 V2 -12 V 5 VSB
Current 22 A 20 A 16 A 16 A 0.3 A 1.5 A
