I was running a Asus ROG B450 gaming-F, ryzen 5 2600, and a gtx 1060 3gb and a antec 850w. I bought a 1660ti, so I swapped the 1060 with the 1660ti. The 1060 has a 6 pin connector and the 1660ti has a 6+2 pin. I plugged the 6 and 2 pin connectors, powered on the PC only to get this message: " Power down and connect PcIE connector... " . Should this not be plug and play?
