Good point. We first used a standard laptop brick (19v x 4.5a) with our
router (the one using the Congatec board), and had horrible heat issues.
Switched to a slightly smaller one (12v x 5.6v) for a savings of over 20%,
and the device ran much better. Cooler, but it still could have run on
probably 1/2 that, but we did not have a smaller power supply. More power
is not always better.

The power supply can make a big difference. If you run an Atom 230, or
whatever on a 500 watt power supply then there will be more wasted power
than if you used a 80+ efficiency 100 watt power supply. Power supplies
generally get their highest efficiency near 50% of the rated watts output.
They may have used one power supply, large enough for all systems tested, so
that there would be less variance between systems (caused by different power
supply), however, that power supply would have been big enough for those
more power hungry systems.
