Notes

1. Airflow of the A239A Power Supply is from the power connector to the ejector.
   
2. Power Supply Efficiency affects the current draw in AC Watts from the branch circuit.
   As efficiency increases, the current draw in AC Watts decreases.
3. To calculate maximum theoretical current draw in AC Watts,
   multiply the maximum power supply output in DC Watts by
   the reciprocal of the power supply efficiency.
4. Theoretical values are typically higher than published values
   which are based on measured outputs under controlled test
   conditions.
5. A two-CPU X4470 will run at 110V input.
   A four-CPU X4470 requires 220V input.
