Ways to connect a PCI-E GPU via USB?

[milbest20]

I've run into an issue, in my 7x GPU rig (yes, for mining), where the 7th card connected to my motherboard (Z87-G45) cannot be used due to "code 12: not enough free resources." If I can somehow run this GPU off of USB or another non-PCI-e interface, this should solve this problem.

I use USB to PCI-e risers, like this: https://bitcointalk.org/index.php?topic=392536

It connects to the GPU via PCI-e, but theoretically I could plug the other end directly into a USB port, while giving the card power as usual via SATA. Could this work, and would the PC recognize it? Thought I'd ask before I tried and fried something.

Thanks

Not possible, they are electrically incompatible , you would need a uC/converter to convert pci-e to usb 2/3

You are better off looking at a thunderbolt setup or pci-e switch based external rack
