So I just purchased a xfx radeon hd 6850 (HD-685X-ZCFC) and it runs great and beautiful on my rig, but I'm confused on why my 6850 need two 6-pin pci-e power connectors? I've read reviews praising one of its big pros as having only 1 x 6-pin to save power consumption. I also read a guy leaving feedback on newegg praising the fact that the same exact model had only one. Even according to amd the 6850 should have one and the 6870 should have 2...SO WHY DOES MY 6850 HAVE TWO!!! I've searched online and can't find any info. Is my card using more power than a regular 6850? Is it less effecient? was there a redesign? Am I using 6870 architecture? I can play it and it runs but i want to know if im getting screwed over when it comes to power saving?
