So i bought the supplies to make my own ambilight system with an arduino and i completely skipped over the part where i needed 5v - 10amp power supply. I was trying to use a 5v 2amp power adapter but no leds are turning on. So i remembered that i have an old pc my grandpa was going to throw away that i got off him, i took out the power supply and it says it will provide 5v 15amp but im wondering if that will be too much cause the post here: http://www.makeuseof.com/tag/make-ambilight-60/ says i only need 10amp and im wondering if the +5 amp will be fine to use. Im using 2 x WS2812B 1 meter 144 leds per strip. I'm not very knowledgeable on the hardware/electronic side of things. Here is a picture of the power supply:
