Hopefully Gigabyte updates their software to support the Wraith Prism better. So best option at this stage for me anyway is to leave the 4-pin RGB connector off, connect only with the USB header and use the Coolermaster Wraith Prism utility for full RGB control on the Wraith Prism. Buongiorno,ho un problema con rgb fusion ho una aorus b450 elite con la versione del bios 4.1.ho provato dopo aver scaricato lapp center ho provato a lanciare lrgb fusion si apre ma dopo pochi secondi si richiude in sequenza e davvero non so che fare.ho pensato di aggiornare il bios ma non. It defaults to the 4-pin mode and RGB Fusion overrides it (back to rainbow ring and white AMD logo only)

Here's the thing though, if you've plugged in BOTH the 4-pin connector and the USB connector from the Wraith Prism to your motherboard, the Coolermaster Wraith Prism Utility will not take control. But you will lose that SYNC functionality with RGB fusion. When the Wraith Prism is connected to your motherboard using the USB header, the Coolermaster Wraith Prism Utility will have full control over all zones on the Wraith Prism including chase effects etc. When the 4 pin connector on the Wraith Prism is connected to your RGB header on the motherboard, RGB Fusion will control and sync the Wraith Prism Fan LED, but NOT the outer ring LED or the AMD logo LED (these will always remain at default which is rainbow for the ring led and white for the AMD logo) I also had these issues and this is what I've found from my testing. I recently bought the 2700X and Gigabyte X470 Ultra Gaming.
