Interesting I have not thought of this. I was planning on running mine off my laptop. Will I be able to run it of my laptops power or will I need a PSU?
Edit: Im only getting one 20 chip board.
burnin stated in the first post that the 20 chips board will consume ~40Watts @ 12 Volts. So yes, if you have a Laptop PSU thats rated 40+ Watts at 12 Volt, it shouldn't be a problem.
