Quick question that I'm sure many of you have solved various ways.  Any thoughts on the safest way to power the 7th GPU(1070)/riser with an EVGA 1300 G2?  Custom adapter cable? Molex to 6+2?  Two of the VGA cables have a split connection from the PSU, but I didn't want to connect two cards and two risers split twice from the same cable. 

Thanks for any quick thoughts.
