Display issues

[Fringedabyss]

I'm upgrading my system from a GeForce gtx 410 to a 680 my issue is when I boot up with the 680 I get no display all the six pin power cables are plugged in and it's correctly seated on the PCIx 16 slot. But when I hook up to the integrated graphics or my old GPU it boots up fine and I get a display any ideas?

Thanks

It could be that the 680 is broken or that it doesn't get enough power,the first would be my best guess,so i sugest if you can try it on another system to see if it is working properly.
