Good day Kuschi
I have a Gigabyte board B550 Aorus Elite and the Thermaltake controller as a combination. The connection cable from Thermaltake to the board was a three PIN connector. There are 2, 5 volt addressable connectors on the board. However, the PIN socket is equipped with four PINs. However, only three of these PINs are actually connected to the board. I crimped myself a connector that had four pins and crimped the three cables from Thermaltake to the correct PINS.
Unfortunately I can't upload photos to show it clearly. (
