13.2.3.8 Power Recovery
The power supply recovers automatically after an AC power failure. AC power failure is defined
to be any loss of AC power that exceeds the dropout criteria.
13.2.4 Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels; 100%, 50%, and 20%. Output shall be loaded
according to the proportional loading method defined by 80 Plus in Generalized Internal Power
Supply Efficiency Testing Protocol Rev 6.4.3.

The power supply passes with enough margins to make sure in production all power supplies
meet these efficiency requirements.
13.2.4.1 Standby Efficiency
When in standby mode; the power supply draws less than 1W AC power with 100mA of
5Vstandby load. This is tested at 115VAC/60Hz and 230VAC/50Hz.
13.2.5 DC Output Specification
13.2.5.1 Output Power/Currents
The following tables define the minimum power and current ratings. The power supply meets
both static and dynamic voltage regulation requirements for all conditions.
