  • powering lcd off of computer power supply

    Ok so if I buy this ps:
    http://store.mp3car.com/M1_ATX_90_Wa..._p/pwr-008.htm

    I would want to use it to power this and this. I can't tell by the description of the touchscreen what the connection type is for its power cord. If its a molex connection would i just connect the screens power cord to the empty floppy drive power source (which is also molex?) on the power supply?

    Thanks guys,

    -Will

    Either the FDD power conenctor or a HDD power connector.
    You're going to have to make your own cable. Remember thast YELLOW = 12v.
    Have you looked in the FAQ yet?
    How about the Wiki?

      Ok, I just wasn't really sure if the floppy drive power source was 12V. Thanks, Darque.

      Btw, is yellow a sort of universal color for 12V? Like if the screen came with a car charger would it also have a yellow wire or would it be red?

        No, it's not a universal standard.
        Inside every PC I've ever worked on, a yellow wire from the PSU has been +12v, though.

          Yellow is the 12volt rail for a power supply; however, this convention does not necessarily carry on to all devices. You will more than likely have to refer to the documentation that will accompany your lcd. For example, if my memory serves me correctly, the +12 wire on a lilliput has white dashes on it (Its been a while since Ive been in my dash, so I am not completely positive).

            would it be possible to splice pc power wire into screen power wire, and hook that wire up to a 12v cig lighter inside dash?

              More details about "PC power wire" are needed to answer this question.

                I'm just going to connect it to the fuse box.

                  Do you plan to use a voltage regulator?

                    I think my PC has a voltage regulator already built in. The PC normally connects through the cigarette lighter port in my dash, but I just cut the male part of cig lighter off and am going to run it through the fuse box with this:

                      I would encourage you to 'Know" then decide the best way to wire it.

                        this is the computer I have.

                        You can see the power supply and everything. I am pretty sure the power cord regulates it.

                          Think and pretty sure... if that is a good answer for you then it's all good. Not my preference but it is your system.

                            I tested it. It works. No voltage peaks or anything that would harm the computer. Drove to work with this setup. Thanks for all the help guys.
