Whats the power in a 2 phase system?

I have an old machine that works across two phases of a 3 three phase supply.
the third phase is not connected.
All the books I consult show me how to calculate power in a single phase or three phase circuit but never in a two phase circiut.
I know the Voltage, Current and power factor of both phases
Is the total power the sum of the two phases or is there another calculation that is made ?

It's the sum of the power of each phase.
