Yet another m1-atx problem HELP!!

**blasterguy128** · 05-27-2005, 09:14 PM

I have just soldered the bottom two pins together and it worked. I tested it and everything seemed to be running perfect. So I put everything back together and recoonect it to find out it has stopped working.

So I whip out the voltmeter and start testing. The problem is I am not sure what is supposed to have juice and what isn't because I didn't test it while it was actually working. So here are my results can you tell me if they are right or wrong?

Battery + - are fine.

Fuse is good. And there is juice running through it when + - are connected.

molex connectors have nothing. (normal I believe)

20 pin connector- all have 12v (except for white wire) when connected to battery negative. (abnormal I think)

Ferrite block (FB1)- 3 pins have 12v and the one I soldered has no juice. I thought this was a problem, but when it was working after I soldered it, it also had no juice. Plus the pin next to it had no power. I'm very confused, what should be powered?

Then I connected the green pin and the ground next to it on the 20 pin connector (cause this turns on a normal psu). Same results.

I know it will work, I am so close I can taste it. Victory will be mine (with your help). Help me conquer the m1-atx.

I'm not an analog expert but most likely, bridging the ferrite bead will probably only marginally reduce the ability of your PSU to block unwanted noise and spikes on the input side.

You measured 12V on all ATX pins? Uh, that's bad -- and it's hard to imagine a failure mode that would produce such a result without some smoke. Dunno how easily you're going to get warranty support now that you've soldered on the board.

Thanks for the help rando, I appreciate it. I think I just joined the "I fried my m1-atx" club.

I am going to mess with it some more, but I will probably end up getting another psu. Which one, I'm not sure.

I know the warranty is voided, but do you think I can pay mini-box to repair it?

Maybe I will just buy a new one and sell this m1 cheap for someone who wants to try to repair it.

I blew my M1-ATX earlier this week and sent off an email to mini-box, haven't heard back from them yet so I wouldn't hold your breath.
However if you want to PM me, I could buy your PSU off you, I've got two blown M1's, between the three of ours I could repair two of them.

You'd have to contact them to find out.

I have sent 3 e-mails over a 2 week period and still nothing.

But the 1st two were sent to support@mini-box.com and that didn't work so the 3rd I sent to m1-atx@minibox.com. Still no word.

I have already purchased another m1-atx, but I would still like to get this one fixed. I am going to call them when I get a chance.

If I can get it fixed then I will explore my options. I could resell the one I just bought, keep one for a back-up, or possibly use two in tandum for more power.

I don't think I need two m1-atx's in my car, I just don't need that much power. Unless I do two computers...Hmm........O no here I go again...

I'll post how things turn out. That is if I ever get some support from mini-box.com

Well, of course, after I just receive my new m1-atx mini-box.com sends me an e-mail.

It was a very good one though. Basically all it said was give me your address and I will send you a new one. Just send the old one back.

So I am very happy now, I think it was just a matter of using the right e-mail address. Now I just have to figure out what I am going to do with the 2nd m1-atx.

Man, I thought since I soldered the board that for sure they wouldn't replace it, guess I'm lucky.

Excellent!

I can't vouch for there warranty service. Normally when something dies on our systems we just end up eating the cost but I will say Mini-box makes an excellent power supply. Lets not forget the options here, do you want to go back to the 60 watt morex or mess with a seperate shutdown controller and Voltage Regulator.

Only problem I have had with our stuff is the 12V line can't provide many amps.
