    Question Help with Arise 865

    I have had my Arise power supply for about a month or 2 now, but I have been waiting on my motherboard that was damaged to be replaced. Now I am trying to get it all together and when I give the power supply 12v dc from another ac-dc PSU the Arise will not power up. The fans turn slightly and then stop. Do you have to have the Arise PSU plugged into a motherboard for the HD connector to have power. I tested the plug with it pluged into a motherboard and not pluged into a motherbaord (no power). My motherboard is a 586LMR and I have read that some need powergood and some don't (heard both about this board). I tried the reset trick but it didn't work. Can I use the powergood section off of the power supply that is powering the Arise to see if it is the power good that is not allowing the PSU to power up?

    Ok now I am confused. One thing I am not confused about is that my board does not need a power good (whew).

    I have 2 case fans (one connected to the motherboard and one connected to the power cable). I also have a CPU fan, laptop hard drive, DVD rom and floppy drive.

    I got frustrated and I unhooked everything but the CPU fan and the case fan that is connected to the motherboard. I connected the Arise to the motherboard and that is it.

    I used the PSU that is powering the Arise and plugged in the case fan and laptop HD to it as if I was using it. Can you believe this it powered up with nothing connected to the power cables of the Arise?

    Were all of these things connected to the Arise too much for it, causing it to not power up?

    I know I can plug the two case fans to the 12v dc of the car but what else can I plug into the unregulated 12v dc of the car with messing anything up? Obviously the Arise 865v wouldn’t run everything that everyone said it would.

    Now I went back to check everything out and the computer was dead but the fans were spinning that were pluged into the ac-dc PSU. I don't know whats up??????????

    I have been playing with everything to see what the DC_DC PSU doesn't like. I pluged evrything in one at a time to see what causes the problem and when I pluged in teh HD it wouldn't Power up. I can plug the HD by itseldf and it will not work. I am really thinking that the AC PSU can't handle the amount of 12 v amps needed that is what is causing the DC DC PSU to not pwoer up. The laptop HD is a toshiba (+5 v dc .7a). Sorry for the long postsjust hope to give enough info to fiq out the problem. I have a fluke but I don't know how to check the amps just volts...LOL don't know much about electronics>>>

    I fell like I am talking to myself here!!!

    Well I got it to work but I had to plug the AC-DC power supply into an old motherboard in order to get enough power to the Arise to get it all to power up. After using the computer for a while i heard a pop in the AC PSU and found that I blew the 250W PSU. What would cause that to happen?

    Buddy u sound lost .........

    Wat i feel is that there is some wire short in your AC-DC PSU which might have happend during R&D so check for it.

    Further when ur powering your Dc-Dc Psu use the black for ground and the yellow wire for the Positive from your AC-DC PSu ..(if ur using a common AC-DC computer power supply)

    also try the power from diffrent source like another connector from the AC-DC pSU...

    Good luck

    sounds like the AC-DC PSU was bad. arise dc-dc is a very nice unit. Had this problem as well and it turns out to be where my power was coming from not my arise unit.

    Also the Arise PSU works just fine with just the hard drive connector pluged in I know cause its all I use in my setup
    Awol

    Cool

    From what I can make out, it seems that you are powering the Arise supply from an AC-DC power supply? More than likely, your AC power supply cannot handle the surge current the Arise supply generates, and goes into current limit. This prevents everthing from starting up. Try using a large 12V battery to power the Arise supply. It should work.

    Or get a benchtop supply from Radioshack or someplace. There are a bunch with 13.8V output to simulate a car's electrical output.
