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?

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.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
