    power supplies and over voltage on car pc .

    im just wondering if i should just buy the right power supply or can i just make this one work .im using the picoPSU-160-XT with a H67s motherboard and i know that this power supply isnt like the others since it cant be configured. also i've noticed this PSU doesnt like anything about 13v's when powered up .i did a test setup in my car and it worked for a good 30 mins up until i got on the parkway and the voltage went up then it shut down . is this more designed for inhome use then automotive use ? it doesn't make sense to make this and not have it be able to cope with a higher voltage . or maybe i can build somekind of voltage regulator ? any advice?

    You're wondering about that?

    im using the picoPSU-160-XT with a H67s motherboard and i know that this power supply isnt like the others since it cant be configured. also i've noticed this PSU doesnt like anything about 13v's when powered up .i did a test setup in my car and it worked for a good 30 mins up until i got on the parkway and the voltage went up then it shut down . is this more designed for inhome use then automotive use ? it doesn't make sense to make this and not have it be able to cope with a higher voltage . or maybe i can build somekind of voltage regulator ? any advice?
    No, the Pico units were not designed for automotive use. PicoPSU requires REGULATED 12v input. Your car's electrical system doesn't supply regulated 12v input.
    You need a PSU that will provide that regulated 12v input (such as the Carnetix P2140 or the DSX12V.

    Honestly, though... If you're going to spend that much on a PSU to power another PSU, wouldn't it make sense to buy an ATX-compliant PSU and be done with it? Something like an M2 or Opus would be dandy for your needs.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.
