  • DSATX starts fans then dies.

    Hey, i just hooked everything up. turned on the ignition the mobo LED went on, the fans started spinning (NO MOBO BEEP or POST and my screen isnt hooked up yet) after about 5 seconds everything shuts off, however the DSATX is still running (LED glowing red), when i turn the key off and take it out the DSATX led turns off. Blinks twice.

    im running an AMD Sempron 2GHz, 1CD and 1HDD..

    what could be wrong?

    Is the DS-ATX (or your mobo) new to your system, or was it working and this is a new problem?

    I would check the mobo power-switch polarity.

    -iTox mini-itx mobo, Core 2 Duo Mobile 1.66Ghz; 2GB, 80GB 2.5" HD, DS-ATX
    -Transflective 8.4"
    -XM, iG4, OBD-II (BR-3)
    -Rearview camera with auto-switching (modified cheesbox)
    -Slim Slot DVD+RW
    -RR, DFX 4

      everything is brand new and never been used before. i've triple checked the mobo power-switch polarity and its fine.

      it turns on for a few seconds and automatically shuts off, no beeps no nothing..

      is there a way to know if something is fried or not..or am i gonna have to hook the mobo up to a AC-DC PSU and see if that works??

      P.S.: mobo uses 24pin, DSATX has 20pins..ive read that 20-24 converter cables dont really do much and every 24pin is compatible with a 20pin. can that be the problem?? my 4pin is connected to give the CPU power.

      thanks.

        What happens if you remove the jumper between the mobo and JP1? Does it still turn off?

          im sorry i dont quite understand, i connected the power switch between the mobo and PSU to G1,G2 (1st row) triple checked the polarity. I didnt set any jumpers on the rest of JP1 its all clear.

          in the quick installation steps there are also these.

          1) Set P1 to set the time before shutdown. Adjustable between 0-20 minutes by default in Basic Mode.
          2) Set P2 jumper to set the low voltage cutout voltage. To minimize this feature, set it to 10 volts (fully
          counter clockwise). P2 is adjustable between 10-12 volts.

          Do i need to do this..because I skipped these 2 steps all together...

          just to clarify, the PSU doesnt turn off. the mobo turns off..but the PSU doesnt. Also when the mobo first turns on, it startles a little..for instance the case fans begin to spin up and then the CPU fan..im sure thats fine and has nothing to do with this problem
          any help would be appreciated.

          Also i am running a 10gauge (10ft) wire fused with 30amps to the VIN, and the same from GRND to negative terminal.

            My motherboard turns on for a second the first time i give the dsatx power too.

            You really shouldnt have to mess with p1 and p2 to get it working. But set p1 to max time and p2 to full counter clockwise for now.

            Try reversing the small 2 pin power button plug on your motherboard (that comes from the dsatx), they are mislabeled sometimes.

              thanks, but i think i got the power switch correctly. because it wasnt powering up at all before, but now it is..ill check again and try it (ill reverse again and see if that works)

              i really didnt want to mess with P1 or P2 but i guess ill have to.

              ill set P1 to max time and P2 to 10V (full counter clockwise i believe)??

              I'll also check my circuit with a voltmeter and report back here.

              any other suggestions??

                ok here are a few tips..
                1. does your mobo has a 4Pin power in adition to the 24pins?? did you hook it up
                if No 1 is OK then
                2. your mobo might be using an inverted power-up logic..check Jeff's pages for info on how to make a cable for thos mobo's

                  yes the 4PIN is connected.

                  if i connect the case to the power switch and then just use the case to power it up, that should solve the issue temporarily? (issue of inverted power-up)..

                    yes i guess so

                    that also happens if the supply voltage is below te setting (set by P2) it happened to me also when i was testing my carpc using an old desktop PSU which was supplying 11volts instead of 12..
                    you should really hook up a screen to see if it is posting..

                      i switched the MOBO power switch and its working fine now.. YAY

                      the wires are reversed for some reason ????

                      oh well atleast its working

                        alright, so i rewired everything in my car and left the computer the way it was when it was working.

                        im now running a 4AWG wire to a distro block with a 8AWG from it to VIN
                        im running a 8AWG from ground on DSATX to distro out of which 4AWG to a chassis ground.
                        and same old ACC line that i hade before.

                        now i am getting 5 blinks. also when the ignition is off it blinks 3 times and turns off..then sort of blinks twice...then 3 times again..all kind of weird pattern.

                        what could it be??

                        if i were to disconnect my PC from the batter what are the steps i would take. I am using TOP posts on my battery as to not interfere with my side posts for the car. Would i remove the ground from DSATX first then take the POSITIVE connector of top post off my battery??

                        and last but not least.. can i leave the setup the way it is overnight...connected..but not working. or is it better to disconnect everything, i am not entirely sure on what to do.

                        my wire connectors to DSATX are all messed up, where can i get some new ones?

                        thanks in advance.

                        EDIT: just went back to the car almost 2 hours later and it is still blinking. i dont want it to kill my battery so i pulled VIN out then GROUND ( i know i shouldve done in reverse if it matters) .. anyway noticed that my ground is very loosely connected to the wire terminal..could that be the problem? is there a way to check a proper ground wire?

                        i need new connectors to connect to the terminals in DSATX and every other one are too wide..

                            so i did some searching around. going to reconnect everything again today and make sure im proper connections everywhere..maybe it will boot up.

                            im just hoping its not one of those faulty DSATX..i had it working the first couple of times with my previous wiring.
