Notes
- Power Supply Efficiency affects the current draw in AC Watts from the branch circuit.
As efficiency increases, the current draw in AC Watts decreases.
- 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.
- Theoretical values are typically higher than published values
which are based on measured outputs under controlled test
conditions.
- A two-CPU X4470 will run at 110V input.
A four-CPU X4470 requires 220V input.
