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 87 W TDP processor (see
Section 1.4 on page 14 for information on supported processors), up to 16 GB DDR3
memory, integrated graphics, one hard disk drive, one optical drive, and all board
peripherals enabled, the minimum recommended power supply is about 260 W with
current ratings as listed in Table 32

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.
