The Phanteks RGB LED strip had one plug and one socket with square pins. My Asus board has two 4-pin connectors with round pins for the LEDs (ASUS AURA). That's why the adapter cable is needed, because the square sockets don't hold on the round pins on the board. The two Phanteks RGB LED strips (400mm) could also be hooked together and operated with only one connector on the board. I don't know how many RGB strips can be connected to each other, or how much current the board can supply to the connection. However, you have to check yourself which connector/technology you have on your board or on your favourite LED strip.
