In the non-arcade SMPS part of my world, as a general rule 5% of rated
output is usually more than sufficient to stabilize cross-regulation -
sometimes it's a lot less actually.  However, I can't speak directly to the
cross-regulation performance of the Peter Chou supplies as I've never loaded
them in that manner.  But if it's one of the 15A units, I think 1A should be
more than enough.

I am testing a board that takes 12v in.  I am using a Peter Chau supply on
my bench.  As the voltages follow 5v on those I need to load the supply
somewhat to stabilize  Is 1A enough?  

Thanks,
David
