12V Port Confusion (B450 Aorus Pro Wifi)

Mosley21

So I recently bought the board. Everything seems fine, except when I was connecting my 12v cable from my case(Corsair SPEC DELTA RGB). I looked at the cord and noticed it had for 4 plugins, while the board had 5 pins for that port? I couldn't find any attachment for both the case or motherboard respective boxes. I really like this case and I wanna know if there's any way I can solve this before having to replace it with another one. I have images below if that's helpful. Thank you.

There are some RGB headers like this on certain boards. I want to say this is typical of Gigabyte boards? But I don't remember off the top of my head.

You can use a 4-pin RGB connection on the 5-pin port, just make sure you line up the power pin correctly. You'll leave one pin exposed but that's perfectly fine.
