Hello,
I noticed that my PCI cable have splited end to two outputs. Can I run 2 GPUs of one cable or do I have to connect single cable for each GPU?
Thank you for your answers.

If you have a strong enough psu you can run 2 gpu's with one cable.

Tell make and model of the psu and model of the 2 gpu's.

Try with one cable using the splitter.

If that does not work out you go to 2 cables.

Btw......I think your talking about pcie not pci.

OK the PSU is 54A @ 12V

Or 648 Watts. That seems OK but it's probably better to run a cable one for each PSU to avoid unintended drops by tapping one cable for both GPUs via a splitter.

You'll have to make a choice here.
