[SOLVED] MSI Atlas Mystic ARGB 3 pin where does it go?

[WilliamDk]

I recently bought the MSI Atlas Mystic ARGB GPU Bracket, but the included rgb cable does not fit on the rgb header? It has 3 holes and the rgb header has 4 pins? I can't seem to find any 3 to 4 pin adapters.
Thank you.

5v Addressable RGB Connector

5v Addressable RGB headers are found on some of the better more expensive motherboards.

A 12v RGB header connector is for:
4 in. RGB LED Strip Light - 12 Volt - PLT

So there is no way to get A-RGB 5v on my motherboard?
