With so many power supplies out there I always assume most of the time bigger is better. That being said, is this how I figure out what size power supply I need? I am assuming the WS2811 LED pixel node DC 5v will take a 5v power supply, while the5m led digital strip,DC12V input,WS2811IC would take a 12v power supply. I then assume I need to figure out how much power I am using (I think that is called current), convert it into watts, then get the proper power supply taking into account the 85% rule. If so this means I may be on the right track!
