I'm building a PC for a friend using a Gigabyte GV-N960WF2OC-4GD graphics card which requires one 6-pin & one 8-pin power connector. Now I'm looking at a Cooler Master B700 ver.2 700W power supply which has two 6 + 2 connectors. My gut (and maths) say that this PSU will be fine but since I'm not playing with my own money I'm hoping for someone to confirm this for me.
Graphics Card Power Supply – Does 6 + 2 PCI-e Equal 8?
