Power Supply

Looks pretty good!
Enjoy the performance, although I would strongly recommend rendering with one GPU and leaving the other one for 3Ds Max, PHotoshop and viewport performance

Why just one? The * is connected to my monitor. How do I make sure MAX is using that one?

Please check my guide here, you can use the Nvidia control panel to make sure Max is using this 4090
To confirm this, you can open a fresh 3Ds Max session and check the task manager for GPU memory usage for your GPUs. The idling 4090 will show close to 0 GPU memory usage, the other 4090 connected to monitors will show +3 GB of GPU memory usage
