I've had this issue with my Rx 580 8gb. I have the blue ones and It would not work for anything. I bought a few of the white ones * Imo best looking ones , as well as it the only riser to supports every power option * and it worked flawlessly.
** Has a onboard Fuse to Protect your GPU from power surge, also has a better IC on the riser, which will keep your hashrates more stable **
