Pro Max Tower T2 FCT2250, MSI RTX 4060 Ti, power connector problem

I bought a Dell ProMax T2-FCT2250. I want to install my MSI RTX4060Ti graphics card, but the supplied power connector is different. My RTX4060Ti has an 8-pin PCIe connector. The supplied cable in my PC is a 12-pin 600W connector. How do I connect it? Is there an adapter available?
