That will definitely be an issue then. A PSU will gradually lose capability as it ages because of capacitor degradation. If it's rating when new was less then what your graphics card manufacturer suggested, it will definitely struggle now that it's older. My guess is that the 12V rail dips under load to the point where the computer becomes unstable.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
