Don't know what this Bitcoinsupermo guy is talking about. I haven't been able to find a bad Chinese usb 3.0 cable yet. When you use them for risers, the data runs through them, not power. So, it's a different issue then power cables.
Any decent usb 3.0 (not 2.0!) is going to work up to 60cm (I needed 1m once and had no problem either).
I am talking about problems that have happened to me while using them, many times after a crash of a mining rig, 1 or 2 cards were not recognized at first, I had to change places of PCIEX1 risers in order for the mining rig to be with 6 cards functional again. Problem were the cables. Once I changed to some gold quality 3.0 cables (i had standard 3.0 before) this problem stopped happening.
