The naming is horrible; usually you'll see the original as 12vhpwr, and the revision as 12v-6x2.
This card uses the latter. Slightly longer power & ground pins, slightly shorter sense pins.

In any case, it's not really an issue with this card. Both from the alternate cable routing (allows a more gentle bend), and the ~330W rating.
I find I much prefer using only the lower cable in the pic vs that 3x 8 pin adapter up top.
