When I constructed my AppleCrate II, I measured the average power
consumption of an Apple //e main board (no cards) at about 4.2 Watts.

Additional cards can change this significantly, with large RAM cards
and accelerator cards being among the biggest power consumers.

A Disk ][ and Controller consumes very little power except when it
is actually running.

Monitor power consumption ranges from a few watts to over a hundred
watts (for a large color monitor).  Monitors will list a conservative
(high) power consumption on their labels.  CRT Monitor power consumption
actually varies slightly depending on the average brightness of the
screen, but this is typically a negligible effect.

It's safe to say that the monitor will be the biggest power drain
in any typical setup.

There are several variations of the ubiquitous "Kill-a-Watt" power
meter on the market for very reasonable prices.  I'd recommend it
as a way of determining power consumption for your particular system.
