Hmmm it shouldn't be that hard in this day and age to come
up with that kind of current assuming switchers would be
clean enough. I have a home use LED video screen I
assembled/am finishing from Chinese modules that runs on
480 amps @ 5vdc, power supplies set me back maybe $300 or
less. Could probably adjust them down or get similar units
or higher quality stuff from surplus (Pioneer Magnetics, etc)
Switching supplies
can be as clean as you need them to be,
just a matter of proper filtering.
