I hear some people talking about resetting the opus by cutting power to it....I may try this but what is the deal with doing this? Still having same problem.
Can someone help? I have an OPUS 150w and i had it power up my PC and hardware a couple of time last night. I was real excited. Now, I can not get it to power up. Funny thing is, the green wire on the 20 pin connector has 5 volts constant to it (???). This is my problem, I know it.....just not sure what I have wrong? I think the green wire is the "power on" and there should only be power on this line when the key is turned on. Why would there be 5 volts on this line? Does this make sense?
The green wire is PSON and is has a weak pull-up inside the PSU according to the ATX standard. When the motherboard pulls this low, the PSU comes on. The motherboard does this in response to the power button being pressed. The Opus fakes the power button press through the 2 pin header. Try reversing this plug -- it only works in one direction. If that doesn't work, completely disconnect the power from your Opus for a few minutes. Watch the LED on the Opus and report back what you see if you continue to have problems.
Thanks for the help Rando.
Ok I cut power to the Opus for about 10 seconds and plugged it back in. The green light went from 2 flashes to a single flash. However, I checked the volts on the green wire and it is still 5 volts.
When I was testing the opus, someone told me to short the green wire with a ground wire.....then turn my key on in the ignition....and the opus would turn on. Well, this worked fine for me up until yesterday. Now when I short these two wires, the opus powers on with the key OUT of the ignition. This tells me that there should only be power going through the green wire when the ignition remote on is turned on. How odd is this? I still need help trouble shooting why I would have a constant 5v on the green wire with the keys out.
