Planning on getting the gtx 1070 FTW but it has 2 8 pin connections. I have one 6 and one 8 cable, cant find my other cable. So my Question is will the adapter that comes with the card be good enough to use? I have a evga 850 g2 power supply. So i know the power supply is good enough. I remembered reading somewhere that adapters were not good to use do to the 6 pin power limits. Just wondering if that was true.
