    Feeding my M1000 12.85V, will it die soon?

    I know, I know unregulated is bad. But so is having a huge voltage drop and also I don't want it to shut my comp down when I turn my vehicle off, etc.

    So in my BIOS it says im getting around 12.8-12.9 volts steady while my cars running. It always says that voltage. I was wondering if this is within the tolerance level or will it fry my board sooner? It's been running in the car for a couple of weeks now and I haven't noticed any odd behavior. Also, the M1000 does use the 12v rail, right?
    CarPC install is starting to come along again...

    I couldn't even get my Epia M10000 to run without regulation-my alternator puts out around 14.5 volts. Computer would run when the truck wasn't started, but wouldn't once I started the truck. I'm speculating that the Epia has some sort of protection when the input voltage runs too high.

    The PSU you're using probably wants 12V +-5% (~11.4-12.6V)

    When you start the car, you get a big voltage drop. That will turn off your PC for sure without regulation.

    You can put an diode in seriel with power, then volt will go down 0.5 volt
    then you are in range that normal for the board
    Plan for project = 100%
    Part the project. = 100%
    Built...................= 99%
    Finish.................= 99%
    Install ...............= 99% -50%

    thought about that. i was just hoping the voltage doesnt dip down to low while im cranking. i'll test it and let you guys know, unless you think i shouldnt be so paranoid
