  • Trying to understand shutdown controllers, etc.

    So as I understand it, with a 150W Opus PSU, with a shutdown controller, my PC will do the following:

    When I turn the key in the ignition, the PC will turn on.
    When I turn the key off, it goes into standby or hibernate.
    When I turn the key on again, it boots up from standby.
    When I turn the key off, it goes into standby or hibernate.
    *repeat*

    Am I correct? Will I need any software whatsoever, or is it completely hardware controlled.

    Your system board & OS need to support this in the first place.

      If that's the motherboard's duty... then what purpose does the shutdown controller server?

        You don't need a shutdown controller with an opus, it is built into the power supply. You have to set the os to standby when the power is turned off (turning the key off). Also have to set the bios to start from power loss.

          providence, when you turn off your engine, sdc will count (based on whatever set/given timer) and when it finished the given time, it will send a pulse to the mobo as if you press the power button. based on what you set the "acpi" on the bios for, it will either shutdown or standby. the automatic "resume on power loss" will turn the mobo "on" when you start you engine is set on the bios of the mobo, sdc has nothing to do with it.

            The ITPS is a startup/shutdown controller (& regulator) So when you turn on your car, the ITPS sends a pulse to your m/b switch. With the ITPS you don't set your m/b to 'resume on power loss'.

              The purpose of it is to interact between car & PC. How would the m/b know whether the car is switched on or not? The controller recognises which state the car is in. It also sends pulses to the on/off switch, keeps supplying power to the pc while it's shutting down & the car is off, turns off all power to the pc afterwards etc. (depending on which SDC you get)

                  It wouldn't matter if you set "Resume after power loss" with the Opus, because you don't have a power loss when you shut the car off. The Opus continues to get power from the batt even with no key in the ignition (when wired correctly).

                    Opus owner manuals...

                    150w
                    90w

                    On the 90w, removing jumper JU1 will turn off all standby power after the shutdown sequence.

                        your are talking about "surviving a crank". use the search function of this website with this words and you'll find tons of info. i myself have a second battery as my "tank".

                          The Opus has a wide input voltage, which means that even when the battery voltage drops during cranking, the Opus will continue to run. That is one of it's best features.
