RB532 + daughterboard and high power cards

If I use spec of the RB532 rev5 to calculate max consumption , I can put 3 Ubiquity SR2 cards + Ubiquity XR9 on a RB532 + RB502 Board. Am-I right ?

XR9 max. consumption: 1.1 A x 3.3 V = 3.63 W
3 x SR2 max. consumption: 1.1 A x 3.3 V = 10.89 W

Total max. consumption = 14.52 W

RB500rev5 have 16W
