They held off shipping to fix the "Caps blowing" issue. Your unit was likely getting assembled when they made this call.
Haven't heard many more stories about the caps blowing other than Anti-KnC people claiming the boxes blow up and cause nuclear fallout (lol) so shouldn't be much longer.
Yes, and it's the power supply's fault - or is it? Designed to have a motherboard connected to the motherboard connector; a simple 2 pin jumper is commonly used instead; startup current is ramped up until voltage is attained; capacitors charged from a voltage take 5 time constants and 70.7% of the voltage is reached the first time constant so it way not linear but charge a capacitor with a constant current source and you get a perfectly straight charge plot right up to full voltage so a constant current source is used to charge a capacitor creating a linear ramp that they track increasing the output voltage until it's at the required voltage. That capacitor charged from a constant current source does not have to reach 12 volts or even 3.3 volts, it can be a ramp from 0 to 1 volt and can be tracked to control the ramping up of current on the 12 volt line. If the ramp is a capacitor charged from a constant current source on the 3.3 volt line, which has no load output load on the 3.3v line because a jumper is used on the motherboard connector and only the 5 volt and the 12 volt power supplly lines are used, then when you shut down the power supply and disconnect the connectors from the miner, the 3.3volts might remain on the 3.3 volt line of the motherboard connector and it the discharge of the capacitor with the ramped voltage depends on the 3.3v rail going to ground to reset the power supply wake-up 12 volt ramp current, then it's possible to plug that supply back in, flip on the on/off switch and hit the miner with un-ramped current, full current at wakeup, on the 12 volt line and in that instant the voltage goes way beyond 12 vdc.
They can take a power supply, a 2 pins jumper, and a test miner, add 3.3v to the 3.3v line on the motherboard connector with a couple of AA batteries, run the miner, shut it down, disconnect the turned off miner leaving the 3.3 battery volts between the 3.3v and ground on the mb connector, reconnect the power supply to the miner, flip on the power supply and look to see if a miner capacitor goes BANG.
Hell, if I were in the lab I say build a test rig with a peak detector on the 12vdc line and the battery 3.3v on the mb connector the test one of every major brand of power supply to see what the restart peak is on the 12vdc line.
