I don't think you are overcapacity on your PSU, even with the EE 965 presler it only hits 316w.

I would contact your GPU manufacturer there are issues with the 7900gt series memory voltage regulator and heat issues, that is probably related to the crashing and lockups.

Doubt its the PSU, could be vid. card driver issues. Try reinstalling them. Also flash your bios is possible.

It could be heat on the graphics card. Open your case and put a floor fan next to it, see if it still resets.
