I have two EVGA gtx 970 ssc ready for sli, well, almost. During many moves last year, I believe I lost my remaining power cables for my EVGA 850w power supply. After Receiving my second card yesterday I've been struggling to find a power card for my second card. However I can't find the cable anywhere. On my current card I have a 8 pin to 6+8 pin connector, all the forums I've been to people say to use 8 to 6 pin? I know the 970 at max uses 175w. From the 8 pin 150w and 75w from the 6, so It definitely needs both plugged in. Am I correct with this assumption and where can I buy this 1 cable I need. Thanks in Advanced!
