Corsair already sells cables that are compatible with their power supplies, no adapter is needed.
You can still buy the graphics card so that you already have it at home. Buying the power supply will probably be less difficult than getting a graphics card.
It's not about the adapter, it's about the fact that the new power supplies can actively communicate with the GPU through the additional connection.
If you have a power supply that is less than 1000W, I strongly recommend not buying a 4090.
The 4090 draws up to 700W at startup (see Jayztwocent's video where he explains this).
