I hate to give such a non-answer, but the power consumption is so
highly determined by your usage pattern that you really can't do
anything but try it and measure using a very low impedance meter.
When running block-moves you'll probably see around 2watts per
actively accessed chip.  Fedora just sitting around will consume quite
a bit less.  The power will probably be dominated by the termination
resistors of ~150mw per chip, which will be your ultimate lower bound.
