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.
