For this configuration, output power excluding the cooling system is 1010 W.
2
For this configuration, output power excluding the cooling system is 770 W.
3. Calculate input power. In this step, the input power requirements for the example configuration are
calculated. To do this, divide the total output requirement by the efficiency of the power supply as
shown in Table 90 on page
