Hello, sorry if my topic is not in the right forum. I have a big problem ...

First I bought six PCI Extender risers version 6 blue, but when I put in the computer and I plug in a video card and I start the computer, the card runs for one millisecond only the fan and stops then nothing happens. I tested all of them and no one work. My card is GTX 1060 DUAL ASUS, I try with many cards, a lot of pc and it does not work ... Can anyone help me? I use Windows 10, thanks alote.

This is my extenders :
