Nutloose, GPU has one x 6+2 way and one x 6 way power connector. The PSU has two ribbon cables each with two x 6+2 connectors that are daisy-chained together (splitter leads as you termed them). We didn't use the daisy chain connectors, instead we made sure that both of the two ribbon cables were connected when first setting up. So yes configured as you suggested. This was the config it was in when it died.
