I would not power two eight pin connectors from one 8-pin PSU cable. Each 8-pin is rated for 150 W, running two off one cable can overload the cable and the PSU connector. I do run a 8-pin (150 W) and 6-pin (75 W) to the same card off of one 8-pin PSU cable. You can also run two 6-pin risers off of one cable.
Sapphire Nitro+ RX 580 will get 30-31 MH/s on ETH + 820-870 MH/s on DCR at ~180 W dual mining compared to the Nitro+ RX 570 4 GB that will get 28.5-29.5 on ETH + 720-750 MH/s DCR at ~140 W dual mining.
Hi Vann,
Thanks. Its getting bit confusing because someone suggested that I can use a single cable to join two RX 580/8GB GPUs and you advised not to.
Can you please let me how you can do that on

Note: I have 8+6 pins on GPU.As per the diagram, I am already doing this:
