That's brill, thanks. I read similar amount of amps online but wanted to be sure.Those metal power supplies do look a bit precarious especially at the mains connections end.
As I will be using this while my computer is on, would it be possible to use the 5v rail of a computer power supply, via a molex connector at all? Would that offer enough amps that would be required?
Would this be okay? Also, would this be grounded to the power supply or through the Arduino?
