    Opus DCX3 120 problem. Fans spin, LED on, no video

    Hey everybody,
    It's been a while since my last post, mainly cuz my EPIA, Opus, Lilli, and others have been running in harmony for more than 3 years
    It was a beautiful thing until about 3 months ago. My speakers made a loud pop. I couldn't start my carputer ever since. Not so nice for me
    Steps that I took to resolve the issue:
    I got a replacement mobo (Epia M10000) and a replacement Opus (DCX3.120). Everything else stayed the same, 1GB ram, gps mouse, iMate, HD. I also got a new car battery in the begging of November.
    Right now I'm able to boot up my pc at home using a normal ATX PS.
    When I take it to the car and hook it up to my new Opus PS, Opus blinks once every 2-3 seconds, I turn on the ignition, opus comes on solid green, power LED on the PC comes on, both fans (cpu and pc) spin up, but...I'm not getting anything else. No video, no beeps on post, no keyboard, nothing. I tried booting it up with nothing attached, video only, etc.
    I called Opus, those guys are AWESOME by the way, they helped me test my PS, everything seemed ok, at least over the phone. Normal voltage from the battery, normal voltage from OPUS. PC starts up fine when I turn on the IGN, and it goes into standby after about 30 seconds when I turn the car OFF. The only thing I noticed, when it goes into standby, it starts to blink 4 times.
    I saw several similar problems to mine on the forum, but they are either similar but not exactly the same or never been resolved.
    Any ideas would be greatly appreciated.
    Is there something that I need to change in AwardBios on the mobo when I first take it out of the box in order for it to work with OPUS?
    Oh, I forgot to mention that my old OPUS was an old and discontinued OPUS 90W. If that makes any difference
    Thank you

    I have the Opus 120 and I had the same thing happen. Take a volt meter and the Yellow lead on your power supply should be 12volts DC. The Red should be 5v DC. I was getting 5v on the red but only .4 on the yellow. My board would turn on but I would get no post. I bet your seeing the same problem. It's worth checking, Opus worked with me and said the powersupply was good, but I had to argue a little with them. They sent me a replacement and all is well.

    I will check on that. Thank a lot, mrcoolgli.
    I called EPIA last night and they told me that since they don't test their boards with OPUS power supplies, it may be incompatible. I had an M board for three years and I know Opus is compatible with it.
    Do any of you guys use DCX3.120 with VIA EPIA M10000?
    In the mean while I'm going to set up a new RMA from OPUS.

    By the way, EPIA tech told me that there may be a timing issue with the board and the PS.
    But he also had absolutely no idea what an OPUS power supply was.

    I would bet there is no issue with the PS.. I have used it on many different boards. I would think the only problem you might have is not enough power for the board. My board is very low in it's requirements. around 30w...

    Opus issued an RMA for this PS. It's on it's way to CA.

    I thought I'd post an update on this. The third time Opus issued an RMA for this board, I asked if I can send my motherboard along. They had no problems with that. Anyway, I sent in my mobo, memory and my PSU. It came back couple of weeks later with a note attached to the power supply: Power Supply exchanged ver E for ver F. I went to hook everything up right away, only to find out that my motherboard was somehow damaged, i'm assuming on the way to my place. I narrowed down the problem to the memory slot (constant beeps, no video). So still unable to test PSU, I got an RMA from EPIA and three weeks later (today) got another motherboard. After I plugged everything in, everything is working the way it's supposed to. Hooray! I wasn't crazy after all. There was definitely something wrong with the power supply, even though it tested fine on Opus's test bench and showed correct voltage numbers when I tested it myself.
