Just installed my ASUS TUF B850M Plus and found it doesn’t have a 12v rgb header. My case led cannot be used now.

Does anyone know a sata controller I can use to have good rgb spectrum cycling. I wish there was a controller that would convert my 12v signal that could interface with the 3 pin argb but it seems nothing has been made to go the opposite direction 12v 4 pin to 5v 3 pin. People will just say upgrade my case but I like the case I have.
