I am upgrading to a msi gtx 1070 and i was worrying about the power supply. At the moment I have a msi gtx 980 that uses 2 x 8 pin and and 1070 uses one 6 pin and 1 x 8 pin but im not sure where to plug the two pins in for the 1070. My powersupply is the cs750m, would be great if someone would help me
