What's the difference between 6-pin and 6+2-pin power connectors?

It says it has "two 6+2-pin" power connectors. Is that the same as two 6-pin ones?

Thats a 6+2 pin connector, the extra two can be used so that it acts as an 8pin if the card needs it or they can be left unplugged and it is just a normal 6 pin.
