    jcjc5555:
    Im sure the Opus 150 and all the other Opus products you have used are perfect, however the Opus 90W obviously has a problem if it is putting 12V out on the 3.3V rail. I have talked to Kris and he is very nice and assures me he will find out the problem, he thinks he knows what it is but needs the actual unit in his hands, which is why I mailed mine off yesterday. So you need to shut your mouth and quit bashing until I find out what Kris has to say about the problem. I still have confidence in Opus and in no way am bashing them. However you need to calm down until we know what the problem is. Enough said. GO ARGUE SOMEWHERE ELSE.

    Dear DCX3 Owner,

    We have found a series problem with DCX3 DC-DC power supply modules.
    if you have not applied power to the DCX3 DC-DC yet, please DO NOT use it
    until you have read this email and have taken the necessary steps to correct
    the problem.

    DCX3 has a problem when the initial power is applied to it. The noise
    generated at the instant the power is applied to the input terminals causes
    unpredictable behavior in the power supply controller output. This behavior
    sometimes damages the output stage of the power Supply. Depending on the nature
    of the device failure the input fuse may or may not open or the input may be
    shorted to the output in this case it will cause damage to the loads.

    If your DCX3 is already powered up and running then there is no concern at
    the moment. But, When you disconnect the input main power (battery) then
    the above modification MUST BE DONE BEFORE YOU REAPPLY
    THE MAIN INPUT POWER to the DCX3 unit.

    The following modification will solve the above problem. Please take action
    immediately to solve the problem. If you are not able to do the following
    modification and/or if your unit is already damaged then please send it to:

    RMA- DCX3
    OPUS solutions, Inc.,
    6 Reef,
    Laguna Niguel, CA 92677.

    Please include your return address, telephone number, the invoice # and date
    with a heading on the note "RMA-DCX3". If your unit is already damaged please
    indicate with a note "Damaged" on the bottom of the note.

    We will repair the unit/s and/or modify the unit and return it back to you.

    MODIFICATION PROCEDURE
    Refer to the attached drawing for reference/ detail

    Please observe STATIC PRECAUTION when performing the following modification
    and during installation. Ground and discharge the body static charge before
    performing the following modification.

    The modification is simple if you or some one you know with good soldering
    skill. You will also need a tweezer for handling 0805 resistor chip.
    You will need a 15K or 22K ohm 5% - resistor. If you need it we can send it
    to you.

    The problem is solved by installing / soldering a 22K ohm 5% -0805 size
    resistor between the TP2 pad (Round pad) and top pad of D15 (Square pad).

    These components are located just above and just right of the printing "
    PATENT PENDING " on the DCX3 Printed circuit module.

    Please reply the email with the following questions answered.

    My power supply is: Working, Defective or don't know

    If defective, please explain the nature of the failure,
    How and when you noticed the problem.

    Modification will be done by : OPUS or me

    If you are performing the
    modification then do you want
    us to send the resistor: Yes/NO

    If Yes, Please provide your mailing address and telephone #.

    We apologize for the inconvenience and the trouble.

    Regards,

    Kris Ponmalai

    To be short:

    A) The opus 90W is supposed to work with mini-itx motherboard so there's only a few board on the market for this PSU. (Should be easier than the 150W)

    B) For the DOCUMENTED problem...there's no documentation on the website available. So I suppose that consumer should be aware of that BEFORE ordering...

    C)@jcjc5555 For you info I am an engineerÖ

    Exactly! I want people reading this to think twice about buying it. It is a defective product and I hope to deter as many people as possible from buying it. You regularly recommend defective products to your customers? No wonder nobody here has ever heard of you.

    Do not listen to the forum abou tthe psu. They work great and it was only 35 units that had the problem. Also OPUS is fixing all the units under warranty. buy the 90w it is bad ***.

If there was no liability for selling a PSU that destroys the parts that it powered then I think you would see 100 different people selling a PSU similar.

    I just hope that this gets fixed because the Opus seems to be the best option (disregarding price) for powering a CarPC. I didn't have any interest in the 150W just because I don't need that kind of power for what I plan to do so I was only looking at the 90W version.

    wo there big pappa

    I would say that is bashing. As far a shutting up that will never happen. Be sure that what ever you think you know I know more about that particular psu. Also you donít go on a form and talk bad about a company and then say your not. GROW SOME NUTS hamster boy. Stick up for what you believe if you think OPUS sucks then stick with it. DO not backpedal and play "mister I am not so bad crap" You did the bashing and I am un doing some of it. Also if you are not bashing then why you have that ****y quote at the end of your replies.

    If I were OPUS I would put your psu on the last shelf and fix everyone elseís first because of you comments. OPUS must not read these forms and if he does then he must be a nice guy for not say go f your self


    Also donít take it personal. I am sure you are a nice guy just trying to get your pc running and thatís cool but you just may have your head screwed on backwards, thatís all.

    @jcjc5555 please stop spamming in these forum...

    I think YOU are doing a really bad publicity for opus.

    Kriss is a great guy and he is very KIND.

    A problem with a new product can always happen. Now it seems to be fixed so please jcjc5555 STOP.

    Thank you...
