4+4 pin together
Hi there, I am trying install a new PSU into my R9 system and I need some help on connecting that '8-pin GPU_PWR' (circled in photo below) on the motherboard.  [IMAGE] The original Dell psu connected it with 6 pin.The new psu provides me with a 4+4 pin CPU cable and I am not sure if I should connect with 4 pin only, 4+4 pin together or 6 pin instead.
How to connect the 8-pin 'GPU_PWR' on motherboard
