  • AC-DC power supply & shutdown controler?

    Lets say my system is to power full for a DC-DC power supply (DS-ATX). I have a very power full AC-DC inverter that i was going to use for my LCD screen, could i use a normal power computer supply then hook it up to an inverter and incorporate a shutdown controler?

    I was searching and found this http://www.mp3car.com/vbulletin/383433-post21.html

    Would this work? the reason might need a lot of power, is because i have a lot of the supplies already. i have a 1000 watt inverter. etc....

    My system consists of a:

    BIOSTAR P4M800 Pro-M7 775 DDR2 MATX
    INTEL CELERON 356 OEM
    KINGSTON 512MB DDR2 Value RAM Memory - DIMM 667MHz CL5 (KVR667D2N5/512)
    SolidTek MINI TRACK BALL KB-5010U White USB Wired Mini Keyboard with trackball
    LITEON 16X SATA DVD ROM BLACK OEM (SHD-16S1S)
    20 GB Dell Laptop hardrive= 2.5"
    Soon to come:
    GPS, bigger hardrive, DVD burner.

    I already had the supplies around my house.

    What, if any DC-DC supply could power these components?

      You need to read this: http://www.mp3car.com/vbulletin/showthread.php?t=68636

      Why would you say your system is too powerful for dSATX?
      Have you looked in the FAQ yet?
      How about the Wiki?

        Well 25= motherboard + 86= CPU + 25= DVD drive + 8= 512 DDR2 memoryif i upgrade to a bigger HD which means 3.5" because right know i only have 20 GB and want to upgrade to at least 100 GB. 25+25+86+8+new/Bigger HD 25=169 All on the 12Volt rail which the DS-ATX only has 144 capacity. So i don't see how this will work in less i'm missing something?

          Easy.
          Go with a slim DVD drive and a laptop HDD. Neither of those pull from the 12v rail.

          You could also go with an Opus 250w or 320w PSU.

          Personally, I'd look into a setup based on a less power-hungry CPU.

            I assume that the slim DVD drive and a laptop HDD run off the 5v rail. if i did this would i still have room to add a USB GPS,OBD,Bluetooth, etc...

              If i return all this i will loose 15% stocking fee. possible. I was searching and found these products.

              GIGABYTE S Series AM2 mATX Motherboard (GA-M51GM-S2G)=25w
              AMD Athlon 64 3500+ Processor - Socket AM2=35 the rating list shows (32 0r 62 which one is this)
              BUFFALO Select DDR2-667 512MB Memory ( D2U667C-S512/BR)
              My 2.5" HD
              + Panasonic Slot Load DVD-ROM/CD-RW Combo Drive 24x24x24

              if i returnd my stuff and picked these products up would i be able to use my M2-ATX?

              if i could it would cost me another 80, but make it so i don't have to buy a DS-ATX.

              or should i keep what have and and return the M2-ATX and the regular DVD drive and buy a DS-ATX and a Slim DVD?

                Okay, if you intended to use inverter, there is NO need for a DSATX. You want the SDC function only, get the Micro SDC or uSDC. It was selling for about 40 something on the store. It has basically all most everything (SDC functions) from the DSATX. Well, the DSATX was base on the uSDC with more feature.

                If you already has the DSATX, you can use the 12V out (yellow wire) to power a relay to switch on the inverter.

                  Its not that i intended to use a inverter, i was asking if it would work. At this point i returned every thing except the M2-ATX. and intend buy something less power hungry. What do you think i should buy. I will use a slim DVD, 2.5" HD. I have $200 to spend on Motherboard/CPU/Memory, what and where should i buy?

                    I would advice you not to "jump in" and buying part yet. Spend sometime search and read this forum to see what other were using and how it that compare to your plan. This will save you some time and headache down the road.
                    None VIA CPU low power part is hard to come from time to time.
                    It look like you already came by the thread. http://www.mp3car.com/vbulletin/gene...-3500-car.html
                    Again. I wouldn't recommend the M2 to power the hardware from the link above. DSATX, Opus are expensive, and the M2 is cheap for a reason. There are people happy with the M2 but also cry with it burning other components as well.
                    Just make sure that you take thing easy one at a time.

                      On this setup it mentions that it has DC-DC on board what does this mean? and would this along with a slim DVD drive and a 2.5" HD work with a M2-ATX?

                        different take on power source

                        I've been playing with a hp e-pc as a car pc for about two years and to date I have yet to find a perfect power solution. what I think will work for me is if I could get a APC 280 UPS unit to power up in my car. It simply doesn't power up. I believe its either an issue of amps or proper ground coming off the inverter in my car. Has anyone else attacked the power problem this way? I think using the power chute software to control shutdown when it senses a lack of power this issue could be licked. Any and all input would be appriciated. I've alway tried to keep thing on a budget for this project. I found the e-pc for $35 dollars on an auction site. My lilliput screen was $79 bucks I bought a gps puck for 12 bucks and found a tiny usb thumb keyboard meant for ps2 for $10. The APC was a free find from work. I've had every thing working perfectly several times but constantly mess up harddrives because of hard shutdowns. someone needs for find an economical way to do this without shelling out for these dc to dc units that still have catches and bugs.
