I.e., on these 6-pin (2x3) SSI-WS/PCIe power connectors,
there are (2) +12V lines in.  So most included adapters break
out to (2) 4-pin Molex connectors (each with one +12V line). 
While the manuals do _not_ state that the 100+W sucking
GeForce 6800GT PCIe needs 2, independent +12V "rails", it
does recommend you do _not_ use the same Molex "wire run" for
both.  I.e., it's done for wire gage considerations, although
multiple rails certainly helps, I'm sure.
