eGPU external video card connection

[smile]

I need to connect external RTX 3090 graphics cards to my HP workstation.


I wanted to use PCIe extension cables, but they are difficult to use since there are no external port adapters. The extension cables are not allowed to be routed through the holes drilled in the case.



Found these options:

Using adapters is beneficial because it allows you to split x16 pcie into 2x x8 ports. But the price is much higher. Who used these cards, do they work? As far as I know, they are not interchangeable. (https://watchmysys.com/blog/2024/10/gigabyte-mj11-ec1-pcie-bifurcation/)
