The upper and lower row do not have to balanced. Only the total current
(i.e. the sum of upper and lower row) has to be less than 650mA for PSU1 and
1200mA for PSU2.

Provided that there is no 5V supply in the system (A-100AD5 or separate
5V-supply) you need the A-100AD5 to run the A-191. Pay attention that the
current for 5V is taken from the +12 line and has to be added to the total
current. In your example this means a a total current of 610mA (250+310+50).
