Okay TL, this is a problem I encountered recently.. and I'm a bit dumbfounded by the result I had.
Recently I picked up a new motherboard, and I plugged it on some good non conductive blah blah blah to test it. The result I had was the PSU spinning up, and shutting back down, and spinning back up (and this was without pressing the on board power button more than simply once,) and this cycle repeated until I manually powered down the device.
Now this is where it gets strange. In my basement I have 115v line. Unless I'm using the dryer, I don't see a 220-230v line in the house, but when I change the PSU to 230v... the power supply lights up, the fan spins, and the lights on the motherboard turn green as if to say "uh hey guy this is great, where's the CPU and the rest of our components?"
Anyone have any idea what's going on here? I was thinking there is some restriction on the mobo, but that doesn't make sense. This is something I have never encountered before... just looking for some insight.
Edit: Keep in mind before the EU crowd comes in here and starts the bashing, I'm in New Jersey, having to run something that isn't a dryer at 230voltage is not normal.

Hahahaha, I know saracen.. I was considering changing my sig and just going "oh must be ascii in that guy's format, I have no idea who that guy is!"
But seriously.. this is fucking weird. My father who has a masters degree in CS from USC came in the room, he goes, "oh it's working now?" My reply was, "Yeah... I had to.. change it... to 230 volt input..." His reply shortly after was, "Go fuck yourself you know that isn't natural, get this fixed or return it."
Much love though bud, when are we gonna play some games? ^^

Never mind I figured it out, can a mod please close this? Sorry.
(Bad batch by ASRock, after taking a DMM to the capacitors it seems that they fluctuate wildly, which can turn to being a big problem later, instead of just sitting with it and accepting that I need to run at a higher voltage, it is safer to return the product... again.)

Wait a sec...if the actual supply is 115 V and you're setting it to the 230 V setting, that means that you're giving the power supply too little voltage, the opposite of what I think you said. The very beginning of the input stage of the PSU doubles the input voltage if you set it to 115 V and does not double if you set it to 230 V. That way the entire rest of the PSU can be the same and produce the same results if the input is 115 V or 230 V.
If the PSU is getting 115 V and is set to that setting with the errors you're getting, I'm assuming that the PSU is shutting itself off because some kind of over- voltage or current protection is being triggered. With the 230 V setting, the PSU is not getting enough voltage, so it doesn't need to shut itself off to protect itself.
My guess is a PSU issue unless the PSU really works with other computers. I wouldn't be surprised if the motherboard capacitors had strange voltages across them if the PSU was getting 115 V but in 230 V mode. Probably the outputs of the PSU are way off, and the voltage regulation on the mobo is acting up as a result.
About the motherboard coming to life with the 230 V setting: fans obviously can work at incorrect voltages, and so can LEDs (assuming that the LED is just an indicator that there is power and not some output of a smart sensor circuit that is saying that everything is fine and dandy).
edit: Another issue could be bad power from the outlet, but I'm not sure what would cause that to the extent that the PSU or mobo has problems
I could be very very wrong though, just a guess.

Hmm myrm, you raise an excellent point. But the true way to test this is to set up the motherboard to the second PSU, and see if I get the same results when I switch from 115 to 230...
because if I get the same result set from going from 115 to 230 than I know for sure it is not the power supply..
hmm.. food for thought.. also testing.

Good luck, bud!
