The middle pin is certainly connected on both PCIe leads of my Enermax 600W Noisetaker SLI power supply. It has 3 grounds on one side, and 3 +12V's on the other side of the connector.

The pin on the connector from the power supply may in fact be connected to +12V, but the pinout of a graphics card PCI-E power connector lists that pin as N/C
