I can't be sure of anything, but the fact that your motherboard died a week after you installed the new card instead of right away tells me that it's likely that it was just its time to die, and that you should be able to safely use the new card with the other motherboard.
Incidentally, though that GTS 450 is quite a bit more powerful than the 8800GT, it actually draws about 19 fewer watts at load.
