  • carnetix P2140 with Dell Optiplex GX620

    Before you read this issue below, please note that i'm really bad with electronics, so i would appreciate all responses to be in the simplest form

    I got my hands on the GX620 which has a regular home 3pin plug on its PS brick
    on the label this is what it says:
    V:115/230
    A:5.0/2.5A
    Hz:50/60

    I also (finally) got the P2140 carnetix which will power the computer and the lilliput

    Dual battery setup, so carnetix's input will come from the aux battery.

    Issue: how do i power the Dell Optiplex GX620?
    I know i have to hack into del's ps brick (i like it or not!) but whats next after i open up the brick?
    do I have to just re-solder the wires in the brick to P2140? which ones?

    if required i can pop dell's ps brick and post some pictures too

    I am reasonably certain that the motherboard inside the GX620 you have is ATX compliant.
    If that is the case, then the Carnetic unit is not the right DC-DC PSU for your setup.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      Thats what I was thinking too. The Carnetix is more for laptops and Macs, and some specialty cases/boards.

      You should have probably gotten an M1orM4 PSU rather than the 2140.

        Mistake: on the GX620 its a ATX PSU not a power brick

        YIKEES!
        lesson learnt: read read read!


        Lucky me, i can still give back the GX620 and exchange it for the SX270 which comes with a power brick

        i'll get that tonight, but i would still appreciate if someone could help/guide me with what to strip

        Thanks!

          I'm gonna say do a little search, and you could come up with this.

          you'll need to cut the end of the SX270's adapter to open up the wires to hook into the carnetix. Now, check the voltages of the adapter before you start cutting - so you can figure out which wires need to be hooked up to what.

            ur a star!

            i just got back from the garage powering up the SX270

            for anyone else who's looking for a solution, i did exactly as ThunderStick describes it

            http://www.mp3car.com/vbulletin/powe...-question.html

            On the PSU Wire both Primary 12vouts together and both Ground Together.
            Cut the cable in half between the power brick and the connector.
            Solder the leads you’ve just cut to the ends of that like this:
            Red (12vin CPU) to Red (12vout PSU)
            Brown (12vin CPU) to Red (12vout PSU)
            Black (Ground CPU) to Black (Ground PSU)
            White (Ground CPU)to Black (Ground PSU)
            Also, solder the screen (Wire Mesh Ground) to black.
            Fold the Green and Yellow wires back against the cable and tape them up.
            Tape each join up individually, then tape the whole lot together.
            worked perrfect! just had to make sure the output jumpers on carnetix were set to 12V and not 18

            I'm stll trying to figure out the power button and the wires, but i'm sure if i read that thread 20times again - eventually i will get it!

            I will post the pics in my worklog soon

            cheers!

              good stuff - glad to be of service

              Yea, I was gonna mention to have the Carnetix set to 12v, but thought I kinda eluded to it. Good thing you went with the 2140 and not the 1900 - you'd be outta luck

                The 2140 has an internal relay output that will allow you to turn your computer on. It is called the ACPI Relay Output (JP6). If you simply connect this relay output (2 wires) to the power button on the computer it should turn on and off with your car.
