    Opus 150w not switching on the computer automatically

    hi all,

    i have an opus 150w PSU, everything is wired up fine and everything works if i switch the ignition and then push the power button on the PC. but i want the PC to be booted automatically when i switch on the ignition. obviously that is what the green and white wire is for, i have that wired up correctly, i tested the cable it is fine, i have the positive side (green) wired to the positive side on my motherboard (i have also tried it the other way round to be sure)

    but no matter what, when i switch the ignition on and the Opus green LED goes to constant on, it refuses to switch the PC on, and i have to do it manually by shorting out the pins, i have tried the cable both ways round, i have checked both manuals the polarity is right, the Opus doesn't report any faults, but obviously if i don't manually switch on the PC after 10 sec (default time set by jumpers) then the Opus times out and goes back to standby.

    i really am at a total loss here, i have checked all the jumpers, i have used both a car battery and an AC power supply (12v at 7A) and they all run the computer fine but only if i switch it on myself.

    does anyone have any experience with this? i have contacted Opus but no reply yet, and i don't want to send it back if i can avoid it because i got charged a stupid amount of import duties when it arrived, and i don't want to have to pay postage back and then tax again for the new one, (it would actually end up costing more than the power supply did in the first place.)

    i am considering moving to an M4, but it wouldn't fit in the case i have at the moment so i don't really want to do that.

    thanks everyone for your time

    My Opus 120W has been doing this for about a year now. I haven't been able to figure anything out. It started not doing the shutdown properly and now it doesn't do either. And yes, I've tried the power cables both ways...

    interesting, did it work before and then just stop working?

    i am wondering if either there is a problem with the firmware or that the optoisolator that triggers the computer has blown

    also i have read a lot about how the bios needs to be setup but does anyone know exactly what needs doing? ACPI is enabled and the power button is set to instant off, am i missing anything?

    Mine did work and then slowly quit working. It'll still give power if the power button is pushed, but it doesn't do anything automatically like it is supposed to anymore.

    so has no one else had this problem?

    is there any diagrams that show how the power supply works? i want to see which part of it controls the start up and shut down

    Only diagram I know of is in the User's Guide. Here's the one for the 150W: http://www.opussolutions.com/pdfs/DC...-15-MAR-04.pdf

    and the one for my 120W:

    thanks for that, the manuals seem to have a technical diagram but no actual wiring diagram, and the troubleshooting is so unhelpful, it doesn't get more technical than "have you plugged it in?"

    i found a solution to the problem, which was to ditch the crappy Opus and buy an M4 which works perfectly
