    Quote from Opus Solutions:
    The ignition lead is monitored to start the PC when the ignition is turned on and to implement a safe shutdown procedure. It controls and monitors motherboard signals to provide smooth power-up and power down sequences. In addition, it also responds to shut down, stand-by and hibernate modes.
    The power supply can be programmed to shut down the PC after a delay of up to one hour.

    The OPUS, upon ignition getting turned off, has an adjustable timer, after a set time, the OPUS will send an ATX pulse to your MB, depeding on how you have the MB & software setup, the computer will either shutdown, hibernate, or standby.

    Frodo,
    So it will only standby, hibernate or shutdown? Not standby or hibernate and then shut down after a preset timer limit has been reached? Is that from practical experience with the Opus supply? Because I read their text to say that it has the capability to do all three and then shut down after up to an hour of idle time with the ignition off. Am I reading that incorrectly?

    You can have it shut off after 10s, 20m, 1hr, 2hr depending on how you set the jumper. Your computer may have a setting (and in some flavors of windows) to shutdown the computer after being in standby for a certain period of time. The Opus behaves just like a normal atx power supply. with the exception of the automated atx pulse. The atx pulse can put the computer in standby, hibernate or shutdown depending on how your OS is configured. Hibernate is merely copies your RAM to your hard drive and powers down so you can restore the same state when you power back up.. there is no way to go to "shutdown" from hibernate since you are powered off.. but then.. it shouldn't really matter, right? Anyway.. booting from hibernate is MUCH faster than normal booting. Standby is a low power mode, your computer can be configured to remain in this low power mode for a certain period of time afterwhich it will shut down.

    But, like I said, the Opus is pretty much a standard power supply that has circuitry for sending an automatic ATX pusle. It also has low power protection which will forcibly shut down your machine (in case the shutdown process hangs for one reason or another) which would be the equivalent of pulling the plug from the wall.

    I am very happy with my Opus, and I'm glad I got it.

    It either instantly turns off when you hit the switch or turns off after an ammount of time set by the variable resistor knob. IE a few seconds or a few minutes.

    You're reading it incorrectly. The power supply has a timer for when it sends the atx pulse. It does not have a timer to cut all power, unless battery gets too low.

    How much power does the opus drain after it sends the atx pulse and the computer is in hibernate? Will it kill my battery if I dont use my car for a couple days?

    not much, and very unlikely, you can probably go a few weeks with a good battery

    But it all depends on what the computer still has running

    Alright, good to know. What would draw power when the computer is in hibernate usb, the hard drive? Maybe Ill get some kind of kill swith that I could use if I know I'm going away or something.

    Thanks

    when a computer goes into hibernation it doesnt draw ANY power. Everything is switched off..

    I think you have that confused with unplugging the computer. What is the point of having the +5 volts standby then?

    There are two kinds of hibernation that I know of. Suspend to ram and suspend to disk. If you suspend to ram, the state of the computer is maintained in memory and the standby voltage keeps the memory refreshing. This takes a few hundered milliamps of +5 standby. Depending on several factors, this can vary to the point where if it was around 400 milliamps, it will kill your battery in a few days or so, if it was around 70 milliamps, it would kill your battery in a few weeks.

    The other kind of hibernation is suspend to disk, lots of laptops do this, they write all there memory contents to disk and tell the system, next time I boot up I will load this file back into ram and leave were I left off. In this case, the +5 volt stanby is just running wake on lan chips, USB, the power button, etc..

    Either way, the opus keeps the +5 volt standby going and it will draw power from your battery and slowly drain it. The only way to avoid stuff like the power switch and USB from drawing power is to disconnect the main +12 volt input of the power supply from the car. An external shutdown controller or a relay will do this.
