Resolution
The following is an example of how to calculate the power consumption of a Quantum system.

Assuming that the Quantum rack contains a 140CPS11420, 140CPU53414U and 5 140ACI030 analog IO modules, the following
specifications are extracted from the Quantum hardware user manual.






The total power is calculated as:

(5.1 x 1250mA) +  [(5 modules ) (5.1 x 240mA)  ]=  12495mW=12.495W

Note: 1.) The total power consumption formula described in the user manual for the power supply includes
power supply losses and power provided to the whole configuration. No losses are to be considered on
backplane, because it is passive.

2.) In the formula, the power is not raised at “1”.  The 1 is a reference to a footnote in the specifications
