Because your GPU can only output so many pixels, the number of monitors that you can daisy chain together is limited. This limit depends on the resolution, timings, and refresh rates of the connected monitors.
Is it OK to daisy chain GPU power cables?
If your “high-end” GPU uses 150W or less, then daisy-chained connectors are fine. If it uses more, then you should use two cables with two separate connections to the PSU, or risk burning out those cables (to potentially disastrous effect).
Can I connect 2 GPU with the same cable?
You can use a single cable’s multiple power connectors without fear of harm to your graphics card or tanking its performance. It’s usually fine. Yes, truly.

Can you daisy chain 3090 TI?
Don’t use the daisy chain connectors on the two cables already connected. You want to ensure the 3090 gets all the power it needs, daisy chaining runs the risk of not supplying the needed watts.
