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.
