Guys, dumb question.....

I got 6 x gtx 1070, 4 cards are powered with 2 pci-e Cables that have 2x8 pin each, and 2 cards are powered using single Cables with 1x8pin.
I guess my question is, is there any Power difference/problems if you connect more than 1 Graphics card with 1 single pci-e Cable?

There is no rules : it's depends of your GPU BIOS.
For the GTX 1070, 1 PCIe 8 pins is enough and some cards have only one.
The manufacturer put a second PCIe 6 or 8 pins only for those who overclock a lot they 1070.

It is only 1x8 pin on my cards.
What I meant by my question is that some of my pci-e Cables have 2x8 pins and I have used these Cables to connect 2 cards in 1 Cable.
So thats 2 cards powered up with 1 pci-e Cable. Could this be a problem? Should i only use 1 Cable for 1 card instead?

Would love to know this answer myself.  My small understandings of such things tells me the wires in those cables are rated to carry so much power (current x voltage). Right there it's gonna vary depending on the quality of PSU/cables you bought. For the cables with multiple pin connectors, I'm guessing they would do fine supporting 2x low-powered gpu. Probably less so 2x high-powered gpu.  Where that line sits, and which side of the line holds a 1070....I wouldn't know.
