I just bought an EVGA GTX 980 Classified video card which requires two 8 pin connections on the PSU. My PSU contains two rows of connectors that are labeled 12v6 and 12v5 PCI-E, how do I know which ones to use? I currently have a EVGA 670 that uses two 6 pin connections and it's plugged into the 12v5 row. Should I use the same ones when I remove the 670? The documentation for the PSU says there are 3 8 pin connections and 3 6 pin, but I don't which ones they are, they all look the same to me..

This is a picture of the power supply, my current card in plugged into the first two connections on the second row which is the 12v5. The top row is the 12v6 ones. Thanks for the help..
