So both the supply Voltage and the method of control of the display is different between the two types, and they can NOT be mixed in the same circuit. Thus every Node along the strip can be different at any moment and more complex displays can be made, like a rainbow chasing itself along the strip. When a Node control chip gets a packet with its address it does what the instructions say with ONLY its three LED's. All the Noeds' control chips listen to the Control Line which carries data packets containing an address and instructions. Each Node contains one LED each of Red, Green and Blue, plus a controller chip for that group only. Along the strip the LED's are grouped into Nodes. It uses a THREE-pin connector (like the 4-pin one, but with one pin missing) that provides common +5 VDC and Ground lines, and a Control Line. The more advanced type is called Addressable RGB or ADDR RGB or ARGB. The colours can be changed over time but at any one moment the entire string is all the same colour.

The mobo header can switch those three colours on and off in various combinations, to produce many colours (maybe even different brightnesses). The plain RGB system uses a 4-pn connector with a common 12 VDC power line plus three separate Ground lines for the three basic LED colours. There are two different and incompatible types of RGB lighting devices dominating the market currently ('devices' includes light strips and the RGB lights built into a fan or pump frame). The problem is you have a mis-match of RGB types.
