KNC is claiming that Corsair (one of the most trusted enthusiast brands) "ramps up current too quickly" and that is why a mining board (powered by Corsair PSU) blew a capacitor. Of course the fact that a high current switching supply SHOULD operate that way should be ignored. The obvious explanation is that Corsair doesn't know how to build power supplies.

I don't believe this at all. I have an electrical meter connected to my power supply so I cam see volts/amps/watts. My Saturn starts off at 20 watts then slowly raises higher and higher until full hashing speeds and max's out around 297 Watts. The power supply isn't going to "push" more or extra amps into by itself...it's the draw of the electronics that I would assume controls that.

It was explained elsewhere with more details. That's not normal power on phase, but a specific case when, due to temporary overloading, Corsair PSU shuts down itself. When it is turned on again during 30 seconds after the shutdown, it can then put full voltage (or rather more than that because of inductancy) immediately, what causes great impulse of current to capacitors and in effect can blow some. (Of course this explanation is still simplified.)
If you can simulate such a case, fell free to use meters, but an oscilloscope with memory would be much proper tool.

DeathAndTaxes, your "obvious explanation" is incongruous. Of course they know how to build, but everyone can make a mistake.
Don't judge other engineers upon oversimplified/twisted information passed through a line of people claiming they don't know electronics.
