Might want to pass this along to a Dell Hardware Engineer
Purchased a Nvidia Geforce GTX 680.
Installed it in my XPS 8300 with an aftermarket 600w Power Supply.
System would not post. Brought the card to work and tested in a XPS 630, card works fine. Then installed it in 2 other XPS 8300's at work. System will not post.
Appears to be some sort of compatibility issue?
Anyone got a XPS 8300 to work w/ a GTX 680?
I have not seen any reports saying the GTX680 would work. Some users got the EVGA GTX570 to work but they had to replace our power supply with the Antec Earthwatts 650w power supply.

Almost same setup, OCZ 600w power supply, the GTX 580 works fine. Tested it on now 20 XPS 8300s here at work, none will post. With AMD or Nvidia 580 GTX works fine.
Have someone who is having the same issue with a 680 and of course it must be an 8300 issue because the 680 is a new tech card.
The 28nm and PCIe 3.0 with early drivers are most likely the problem.
This issue is also in other places online.
The fact that the 580s work is irrelevant because it is not the same technology. I am almost certain this is a compatibility issue that Dell will work out. They are good about those things.
I can't see dell not fixing this fast with a bios update.
