For those of you running a large SBC cluster - what is your solution for powering your boards.

 

I currently have a cluster of 18 boards that I am powering with several multiport usb chargers. My setup does work well but I am looking for alternative solutions. I'm thinking of expanding my cluster to 50 or more boards and I don't like the prospect of purchasing so many of these multiport chargers as they're a little bit expensive. And I also don't know about the long term reliability of my current setup as I have only been going for about 2 months now.

 

I would love to hear about and see other people's SBC cluster powering solutions.

 

EDIT: I'm open to all options but some kind of rackmount solution would be best. A lot of the rackmount stuff is very spendy - and I honestly don't mind that if it can power a lot of units. But I am mostly curious about skipping the powering alternatives that don't use the USB port at all. It just seems the best solution when powering many devices simultaneously.

Thanks, Keiser. That looks like a promising thread to read through.
