So far ive got 3 packs of LEDS and for my controller I am using Controller and im not sure what power supply what would be compatible and if there’s anything else I would need.
A rough estimate says each of those strips can draw near 100W.
Depending on the layout you envision for these, you’ll need at least a single 300W supply (or 3 100W if you’re spreading things out).
I think the specs show these as 12V devices? so your main supply(s) need to match that.
It will be well worth your time to draw out your anticipated design and get some expected wire lengths so you can plan your power and/or injection requirements. Those 3 strips can get you into the realm of handling 25A of current (total) so your wiring needs to be up to that.
