Hi Stingi...

 Not faulty risers as have chopped and changed every combination.

 Have the dual PSU cable but it is not helping.


 Seems to me that we need to buy a 1200w PSU but that is not gonna happen any time soon (after our 3 grand initial outlay

There has to be a way of using the two PSU's



 Just how...  

 Gonna leave it with 5 GPU's mining ripple. Should be a Bitcoin millionaire before I know it.
