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 typical system configuration of a 95 W processor (see Section 1.4
on page 14 for information on supported processors), up to 8 GB DDR3 memory,
integrated graphics, one hard disk drive, one optical drive, and all board peripherals
enabled, the minimum recommended power supply is about 320 W with current
rat
ings as listed in Table 27.
Table 27. Minimum Recommended Power Supply Current Values
Output Voltage 3.3 V 5 V +12 V1 +12 V2 -12 V 5 VSB
Current 5 A 12 A 10 A 10 A 0.1 A 0.5 A
NOTE
+12 V1 denotes the 12 V rail at the 2 x 12 power connector
+12 V2 denotes the 12 V rail at the 2 x 2 power connector
