2 7800GT'S on 1 rail????

[Elusiv1]

Hi, I have an OCZ Powerstream 600 psu but my motherboard( A8N SLI Deluxe) has 1 12v connector and the psu has 2 12X cables for splitting the rails. I just purchased a 2nd 7800GT for SLI and now I'm totally confused on how to power them without having the 2nd 12X connector on my motherboard?? My biggest concern is overloading 1 rail, I would appreciate the help...........thanks
