Almost 100% true.

If the thing hits 13 amps, you have a problem. :-)

I would not suggest you look for a power supply if it appears that
13A is not enough.

A little elementary knowledge of electronics will tell you that as long as
the VOLTAGE of the power supply is constant at the right value, no damage
will occur. Problems happen when the current _limit_ is hit and the voltage
has to drop to stop the current rising any more. So if you try to take 1.4A
from a 1.2A supply, the voltage will have to drop by some amount. Get a
bigger power supply, it can't do any harm :)
