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

Can I manualy add power connector to my card? It has not power connector by default, but there are pins for it and newer version have this connector. ASUS X800np
