A power supply of 850W (silver 80+) should run it with no particular problem.
While I deem it unlikely, there still could be a problem with the PSU. Last time I had PSU problems only one of my hard drives kept dropping out and reconnecting, while everything else (including 3 other drives) was totally fine. The 12V rail went down to 10V, yet the system never even crashed.

Regarding the different firmware, well I don't think the difference is a problem as even if the card is solo it aint working, and besides installing/updating the driver, what else is there to do?
I meant the firmware intrinsically running on each card. Running it solo doesn't magically erase and re-flash the GPUs memory. Also I already suggested what to do: try a different mainboard and PSU. There's probably no other viable option left for you.
