My experience with mini-box (maker of M2-atx and others)
seeing as we have a lot of members here that are newbies and do some research, i figured i'd post my convos with mini-box tech support regarding an issue multiple people have had.
this will give you guys a decent idea as to how mini-box deals with their customers, something probably as important as the power specs.
my first email:
i would like your assistance solving this matter. I have an M2-ATX bought 03-08 from one of your authorized resellers (short-circuit.com, reciept available upon request.) i smashed my car before hooking the m2-atx up, and let it sit. upon booting the unit up for the first time recently, it worked fine, with the exception of a broken piece of ram not booting power to the 5V rail (actually i sent a quick support question to you guys, and one of your reps (Cristi Ciubotaru) never got back to me with an answer (support #54620).
i took the unit out and attempting to reinstall it went seaching for the correct way to install the motherboard on/off switch. upon only finding the +/- pin-out for my Via EPIA M10000, i guessed at its corresponding pin-out on my M2. the motherboard failed to boot in sequence, and would only boot when i pulled the connector off the J8 pin on the m2. furthermore the 2 pins on the J8 are constantly shorted.
some research on the internet has led me to the conclusion that when i guessed at the polarity of J8, i guessed wrong. my problem matches exactly that of user "cobase" http://www.mp3car.com/vbulletin/powe...-problems.html
in his case his unit was RMA'd and replaced.
i advocate that my unit, even though out of mini-box's one year warranty, should be RMA'd likewise and replaced. I feel this way because (i feel) the J8/J9 connectors should have been labeled on the either the installation sheet or manual, or maybe available on your website, or something. (in fact, your latest manual still fails to list the polarity of the pins) this is especially pertinent information given the fact that improper installation will toast your power supply.
interestingly enough, there's a big ol' disclaimer warning that reads:
The M2-ATX board has several wires that need to be installed in various
When installing, always double check the polarity of your wires with a
further confusing me is the fact that the J6 connector (which doesn't toast the power supply if switched) has its pins labeled, yet the connectors that fry the power supply if switched aren't labeled to ensure this doesn't happen.
i look forward to your response and a positive outcome for all involved.
