  • Shuttle SN25P proprietary plugs! arrgh! Need to adapt/make a Car PSU for it

    Hi all,

    long time lurker, first time poster. I'm building my carputer, and chose a shuttle xpc SN25P, which seems to have it's own funky power supply that is possibly not compatible with the opus. It has 2 plugs which have "12Vsb" (for 12 Volt standby?) wires and ground wires on them. No 3.3 V lines, no -12V lines, just +12V "standby" lines.




    I would like to adapt an existing car Power supply such as the Opus to deal with this motherboard, or make my own, since it IS 12 volts.

    Could I have some assistance / tips on how to adapt an ATX or ATX+12V power supply to this, or does anyone know of a power supply I could purchase to support this computer?

    Thanks!

    A description of the power supply in Shuttle "P" series cases is here:

    (that computer has the same power supply)

    use the pin assinment chart to splice in your opus if you can.

      If you want a real clean solution Id get a female ATX connector to plug into the Opus' ATX connector. Then from the female ATX connector attach the connectors that are on the Shuttle PSU. Find the parts on the Molex site, they're on there somewhere, just have to look

        I went to an electronics supply store and found a couple of the plugs yesterday, need 2 more and I should be all set! Thanks! I just wanted to confirm that I could just run the wires with the right voltages and connect everything that way

          what is the total power of +12v and the +12SB?

          I can make one for you at the size about 30mm x30mm x50mm

            it looks like splicing the opus is a bad idea. dragonBTV, you have a PM

              you could use a low-wattage ATX DC-DC supply (like the M1-ATX or something), and a separate 12v dedicated DC-DC for the 12Vsb lines. (several dedicated 12v output supplies are available)

              that seems like the easiest way...
              But don't take it from me! here's a quote from a real, live newbie:

                what dedicated 12Volt DC-DC power supplies are available? I don't know of any...
