I put heavy blame on Nvidia for that one. There is no reason their cards should be pulling these huge transient spikes. By putting these cards out with this flaw, then pointing at the power supply manufacturers, they are causing a problem and blaming someone else for it.
The power supply is just doing its job, when you far exceed its rating for even a short amount of time it's going to try to shut down to protect the computer because it thinks something inside of your computer is burning up.
you're right, I forgot about the fact the spikes were far in excess of the TDP of the card, NVidia should have taken a lot more responsibility rather than let PSU mfgs take a lot of the heat.
