In trying to figure out all that I need to get for my RGB. Right now I am trying to figure out what I need for power supplies. Will I need to buy multiple supplies, or is there a way to just have one? I will be using the D4 and the P12R. For example, say I have 4 mini trees spanning 15 feet, each tree using 50 pixels. Then I have 3- 5050 strips running up 3- 8' poles. These poles are 20 feet behind the mini trees. Now say I have 176 pixels around a garage roof another 20 feet behind the 3- 8' poles. Would I need a power supply at each place? Or is there a way to power it all from one supply?
