I've noticed this on various power supplies before.  Some power supplies can
run for quite some time with no power.  Before I ran unix (read: cared about
thinks like fsck) I used to be able to move the power cord to a different
outlet about 4/5 times without losing the machine.  (not one far away.. less
than a second)..  Some of my older machines wouldn't survive any minor power
glitches.

I'm guessing it has to do with how many capacitors are in there and the size of
them.
