Looking at the specs, you say its a 525W PSU? the GPU,while it sucks down less watts, is probably amp hungry. I think you need to back track and reinvestigate a larger PSU. Check your cards system requirements, my 660 Ti calls for 24A on the 12v rail. and that is specific, that means it needs to produce that many amps on one of the divided rails in the system, not as a whole unit.
Ever since the 5k series cards were released there have been chipsets (namely nvidia/intel and a few of the really old amd chipsets) Have not been posting without bios updates from ther respected manufaturers.
But I wouldn't nessassiary place blame on the PSU even though I know its junk(because all dell OEM PSUs are) seeing as how two GTS 450s pull the same amount of power as a 7950, and 1 is only 30w shy of a single 7850 which he's tested.
Replaceing the power supply or testing it with another would definetly be an option to test. but in the end. It may be the deciding factor. Hence why recommened quality PSU's from manufacturers like enermax/seasonic/ corsair / XFX / Zippy / PC power and cooing.
Just for reference a 7950 TDP is 200W.and a 7850 is 130W. (give or take a few depending on manufacturer clocks)
In theory his PSU should be "ok".
