It should be, although depends on the video card too I guess.  I would
be fairly sure the enermax 350 probably handles more load than a
neverheardofit fortron 400.  Quality matters.

Power supplies do also degrade over time as most electronics tend to do.
The better ones handle this better, while cheaper ones can become
