Question First time build problems

[jordo21]

I am building a PC with the Z6901 Aorus with the Kraken X63 AIO. the Motherboard manual shows that the USB 2 header should have 9 pins. However the actual motherboard USB 2 header has 12 pins. And this prevents me from connecting my Kraken USB 2 connector which only has 9 pins.

Either I'm missing something or the motherboard has an extra pin where its not supposed to be?

Will leave post up but found out answer. Apparently many of the connections are proprietary, this isn't stated in the manual and the pictures are wrong. But my Motherboard did come with the adaptors to the proprietary connections.
