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
.Here we include the power drawn by the cooling system.
NOTE:
Normal-capacity AC and DC power supplies are not included in the following
table, because their power budget was exceeded in the sample configuration.

These values are at full load and nominal voltage.
4. Calculate thermal output (BTUs) for the system. To calculate this value, multiply the total input power
requirement (in watts) by 3.41 as shown in
.
