That's a 3pin 5v argb header. Plugs to the board if it has one. And if the board has a 4 pin 12v don't use that, that'll fry the cable.
Mentioned the pin configuration in my feedback. Certain platforms use three-pin connectors while others use four-pin. If your setup lacks the correct type, you won't have many options—just keep the cable disconnected. Some boards even support both three- and four-pin headers, which is why mine works that way.
