Re: [WTS] USB Style PCI-E 1x - 16x Powered Riser Cables !! $17 Each

I wasn't being an ass, you asked a question about a totally different product. These don't connect the power lines. Power is supplied by the molex, I have tested amp draw on all the lines. There is no "current backflow". This is NOT a ribbon cable, but a usb cable. These are designed for this purpose.

If you say so bud. Confirmation that none of the 12v lines were connected back to the motherboard would have been sufficient. I'm aware they are different products, that's exactly why I had to ask the question.

You didn't ask, you said you had seen tons of motherboards fried with these risers. That's not true.

Yes, it appears I slipped in an errant "these" in my original question that did however reference ribbons. I've edited it for clarity, as I was speaking about risers in general, so sorry for the confusion. USB carries power obviously, so it's impossible to know if the 12v line is connected back without actually asking the question.

Standard USB signal cables carries power. This question was asked couple pages earlier if these were a PCIe to USB signal and back conversion, which it is not. The USB cables are just physical wires that continue the flow of PCIe signal between the two boards with no USB conversion. Hope that answers the question.
