XFX 7950 DD - 1x6pin 1x8pin
 

Bought 2 of these from dabs.com, and on the details on every website the card requires on two 6pin connectors.
I took these out of the box however, and they require 1x6 and 1x8 pin connectors for power?
My PSU does have 2 8pins and 2 6pins, but is this some kind of regional difference?

No the DD edition uses the 7970 PCB which why it has 6+8 i guess who ever wrote 6+6 mixed it up with the reff 7950.
