I am currently making a shopping list for an LED light strip (link) and I am getting 3m of it. Now, my main problem is powering that beast.
By my calculations, (42W * 3m) / 5V = 25.2A, if that is correct, that seems like an insane amount of power for such a strip, and any power supply I could find that was > 15A is just a barebones transformer.
They have listed that 42W/m is the maximum power draw, which I am not extremely likely to do, so I am currently looking at this power supply. Would it be sufficient?
