Graphics Card Power Supply – Does 6 + 2 PCI-e Equal 8?

graphics cardpower supply

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.

Short answer:
Yes

Long answer:
Yes you can mix them anyway you prefer to.
Even if it has only 6 pins you can always buy a converter like this

Some video cards have 6 Pin PCI Express power connectors and others have 8 Pin PCI Express power connectors. Many power supplies come with a 6+2 PCI Express power cable which is compatible with both kinds of video cards. The 6+2 PCI Express power cable is made up of two pieces: a 6 pin piece, and a 2 pin piece. If you put the two pieces together then you have a full 8 pin PCI Express power cable. But if you split the connector into two parts then you can plug the 6 pin part into the older 6 pin PCI Express connector and leave the 2 pin part unplugged. That way, your power supply only needs to have one 6+2 cable to be compatible with both 6 pin and 8 pin PCI Express connectors.
