The power budget for each NuBus slot is 13.9 watts, for a total of 41.7 watts, and the power budget for each NuBus card is as follows:
Voltage (V)    Maximum current (A)     Maximum capacitance (mF)
-----------    -------------------     ------------------------
+5             2.0                     1513
+12            0.175                    536
12             0.15                     698
These NuBus power requirements also apply to the Macintosh IIvx and the Macintosh Quadra 650, which both share a common case design with the Power Macintosh 7100.
