Did I miss something? What is wrong with his PSU? This thread is moving too fast.
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.
