  • Which PSU (for QBox-1010)?

    I'm planning to run my Quanmax QBox-1010 mini PC in a car. This box only need +12 volts (no ATX needed), however my audio converter (unbalanced PC output to balanced car system) also needs -12 Volts (negative). Does anybody know about a PSU with +12 and -12 Volt lines? Or should I just go with an ATX power supply anyway?

    are you sure it requires negative 12v? seems odd...

    there are multiple power supplies in the mp3car store that supply +12v, though it might be best to contact them to see if any are capable of negative 12v..

      Actually it requires +12v and -12v as well...

        Ok well... as apparently no one has any better idea, I decided to go with the M2-ATX. ATX power supplies have -12 volts and at least I can eve use it later if I decide to switch to an other PC or something...

          uh, the m2 atx is a atx-compliant power supply, and your board is not atx-compliant, so you need to trick it into working with a non-atx-compliant board...

          you require one of these:

            Correct me if I'm wrong, but I think "tricking" it only means connecting some of the pins in the ATX connector.

            Besides, none of the PSU's you linked are capable supplying -12V.
