Here are my molex chains that came custom from Lepa G 1600w.

It seems like we have contradicting info on this.

Putting 2 card risers on one molex chain (as shown in imgur), or put a dedicate one cable to a Molex>Sata...

I'm leaning towards putting 2 cards on one molex cable for now. However, would the non-standard molex chain found from the PSU be an issue onto itself?

I also have a second rig that'll be facing this same issue. I have x6 XFX 570 RX and need to decide if putting 2 risers on one cable is safe.

Ideas on safe wattage on those?
