It appears nVidia didn't take 6+2pin cables into consideration. Either way, they will not work on the new nVidia cards (with reference cooler) due to a useless shroud. You can remove the clip off the connector, but you'd likely be voiding your PSU warranty by doing so.
Pictures are on the link above.
Edit: Title should say upcoming nVidia card (the 9 series). However I cannot edit my title.
