    atx pin 9

    Hey everyone, got a question hopefully someone can help me out with. I have an vfd accessory that I'd like to power in the front of my car. It has a 3-pin power connector that draws power from the atx cable of the mobo. It uses the three pins showed in the attached image.

    pin 6 is +5V
    pin 7 is Ground
    pin 9 - I've seen this described as +5V VSB Standby Voltage and as a +5V pwr check

    Basically I'm not sure about what to feed the device for the pin 9... because I don't want to splice and extend the atx adapter that comes with the device all the way to the front. Can I simply feed it another +5V?

    Standby voltage is always on as long as the PSU is plugged in (which makes it a power check, I suppose.) Giving it regular ol' 5V should be fine, unless there's some settings that get cleared if you remove power or something. Basically, it will act as if you unpluged the computer rather than just powering down.
