I'm in the final stages of putting my new build together, and I'm looking to make two 1m/60 LED strips with WS2812B LEDs. I'm comfortable hooking one up to a Corsair Node Pro, as the rated output is 4.5A, but I'm going to need two separate strips.
So I'm looking for a bit of advice - can I simply provide supplemental power to each strip directly (using a SATA/Molex to the +5V and GND) and connect the +5V, D, GND to the relevant Node Pro channel? Would it be better, to avoid damage to the Node Pro, to power the strips solely from a SATA connection and leave the +5V from each Node Pro channel disconnected (and in this case, should I connect just the data wire or both data and ground)?
I'm going to be receiving the Node Pro today, and will likely play around with it a bit before doing the build at the weekend (getting my second vaccination on Sunday, so that might put a crimp in my plans!).
