Hello all can some one help, I have built a 480 led matrix, using WS2812 wired up using 20 x 24 strips Wired up in one long snake, I am having problems with the colours changing toward the end on matrix, I am guessing this is a power related problem. I have a 10amp 5v supply and I am unsure if this will be enough to start with or is it just the case of running extra wires with power in random places on the strip, simple question but I know,

480 x 60mA = 28.8 AMP
At full white
I have 400 led running ok in colors with 15 AMP power supply
But with 200 led run full white this power supply is very warm

@wayne_hemmings how do you power your strips ? You should power then individually you will get better results.

Yes, you’ll definitely need to inject power at multiple places along the way, if not for every one, every 2nd or 3rd or 4th. Set them all white and check your power demands are met, and look for them turning red where furthest from power.

Thanks for all the help I now have run extra power to each strip and it’s looking good, will post video when I get a min
