  • Opus 90W - Power but no Boot

    Hey all,

    I have search and search this topic and am sure there isn't a solution on here yet to my problem.

    Problem = My 90w Opus is getting power as indicated by the flashing LED, once every 3 seconds. However my PC will not boot.

    Things i have tried =

    1) Tested the voltage on all lines - getting;
    12v on red line
    12v on blue (IGN switched) line (this also goes once switched off acc)

    So power is getting to the Opus as stated above the LED is flashing - The manual states this the Opus is powered and awaiting the Ignition signal to power on the PC

    2) Checked the wires from JU1 (to send power on signal to m/b) this seems fine and tried switching the wires to ensure i had the correct polarity.

    3) Removed fuse as this has been mentioned in another post

    4) Removed power to Opus removed all wires from m/b - Then reconnected Power then all wires - Still no joy! Again mentioned in another post

    5) Left PC (and Opus) in the house for two days so it is warm as many have stated there are some dodgy PSu's knocking about and thought i may have one. Tried this morning with a nice and warm PSU but still no boot!!!

    Anyone got any suggestions?? I already had an M2-ATX that needs the PIC retiming so got this and it did work for bout a week while i was testing in my car.

    So it doesn't seem i have on of these dodgy PSu's as it doesn't work when warm or cold - just sit;s there idle waiting for the 12V on the IGN line but doesn't do anything!!

    Also the PC works from an ATX PSU indoors!!

    Thanks for any help

    i bet it's a grounding thing. i had issues with that..........did you try regrounding?

      Well i have removed my stock stereo and am using those wires.

      Thinking about it i have just wired my amp so i could use a disto block for power 12v and use the amps ground point.

      What you think? I'm running outta ideas!!!

        I am having the same issues. Ground is good, the mobo is good, I have a blinking lght every 5-6 secs, but no boot.

        I have one fear, That the ground disconneted, and it kept working, burning something on the psu. I reconnected the ground, and it continued working, then i disconnected the + and it didnt work again.

        I checked everything. I plugged it in the power button, and tried to turn it on manually, and it seems the opus psu is just not sending the power to the board.

        I am at a loss.

            Would the opus still get power if there was a grounding issue?

                  I havn't seen or heard anything like that on these forums to be honest. Surely the Fuse would have blown before hand?

                    my stupid opus 90w doesn't work no more. i'm getting a dsatx.

                    it like works when i take the carpc and fiddle with it and then i put it all nice and neat under the seat and start the car and doesn't work again.....so flakey...I'm done with opus.

                      The PS should have a dedicated 12V line (10-12 gauge) going to the PS and for safety should have its own dedicated fuse. Are you using the ground and 12V from the stock stereo harness? Usually those wires (and/or fuse connected to those lines) can't handle the power needed to run a computer.

                      I can't find the 90W manual since its obsolete now, so Iím looking at my 150W manual and it says the JU1 pins are to be jumped to provide the time off sequence. Youíre not connecting the motherboard power switch to that are you? The switch should be connected to the J9 connector. Iím guessing the 150 and 90 have the same pin numbering since they went into production at about the same time.

                        I have the 12v and Ground wired to the radio harness. However i have just wired and amp up so am planning to get a distro block to use the 12V (fused) from my battery to power AMP & PC. Also use the amps ground point for the PSU ground wire.

                        There doesn't seem to be a J9 on the 90w - so must be different. See this link

                          Thats the manual I was looking for thanks. Looks like its the J5 connector (PWR-SW) on the PC Board, highlighted in the image. You're wires should be connected from that to the power on pins on your motherboard and the JU1 should have a jumper on across pin 2. This is how it should be setup, try that.

                            This is how it is currently set up, it has workied in the past which is what doesn't make sense.

                            i have read about the Opus going into 'Protection' mode once full power is lost.

                              Try using another switch. Instead of connecting the motherboard pwr sw to the Opus, use a power switch to see if it will power on or just short the power sw pins on the motherboard to turn it on. From there we can see if the problem is the on/off controller on teh PS, or if the PS is having problems putting out the voltage.
