    Computer Died

    First Post. Please bare with me. I am not sure where to start rebuilding.

    After successfully running a full P3 ATX PC in my truck for many years now, it finally decided to die before show season summer 2008....Oh Joy.

    So now I am here. First thing I would like to do is go smaller. Second I would like to go DC to DC, in hopes of less noise than the inverter. Third from what I understand a shutdown controler of some kind?? for softer bootups and shutdowns on the amps (zzzt, thump), lol, getting tired of that.

    After being spoiled with a full computer I am having trouble scaling down what I have and what I can live without.

    Near as I can figure 250W is the biggest DC/DC psu offered anywhere. And then I think I still need a controller.

    What power supply would be best and is there one with a built in controller??

    I have a power switch wired now from the old inverter and have no problem with reusing using it if I need to? I did not have to have the computer "keyed" to switched ignition. I just used a hidden momentary switch and would like to continue using that.

    Any thoughts to get me started would be much appreciated.

    What do you see as a "full" computer?

    I am running a very powerful core 2 duo (macmini), powered by a Carnetix 2140, and then another setup, also core 2 duo (Merom), based on the Commell LV-677 motherboard, 100 gig 7200rpm 2.5" drive, 1gig ram, etc.....this powered by a M2-ATX dc-dc controller.....

    So yes, any of these will and do easily kill anything P4-based, yet, they are small footprint, low on power requirements, and handles anything you can throw at it....the only thing the macmini won't do well is 3d gaming - the Commell system has an PCI-express slot for a better gfx card compared to onboard, should you want to game....

    Thanks for the reply.

    It sounds like way more than I was planning to run but very helpful to know it is possible.

    As for a "full" computer I am refering to a full size atx board with lots of PCI slots as well as an AGP slot. I was running Pentium 3 733, 1 gig memory, 1 7200 rmpm hard drive, 256 AGP card, PCI wireless G card, PCI Gametheatre XP digital surround card with external rack, 450 Watt power supply, 600 watt invter.

    Admitadly none of this is as high power as your running so I am hoping this M2 ATX dc to dc controller will work for what I propose to run. I am no longer into gaming so thats not an issue as far a needing a PCI express slot or anthing. I just want to be able to run an AMD 64 x2 or sempron, Likely keep the p3 733 it only uses 19 watts, atx board with onboard graphics, my Sound Card, hard drive, CD/dvd writer/reader, and 1 gig memory. I just really want to enjoy my music again and play movies on my big monitor (another issue for another post).

    I think the mac mini is great because it's everything you need, all in one box. Its rated to take like 90w MAX, however, mine has never hit even half that. as for that big monitor you have that pops up, i couldnt tell you how much power that takes, but it may be easy to keep that on an inverter that you only turn on when you need it.

    I use the P1900 which powers my mini and 7" TS with no prob. The lower wattage you use, the less your alternator has to work and the better gas milage you'll get too

    I think I am going to build my own or just be lazy and buy one of the starter kits. There is sooo much to read on this forum, tons of great info. Don't want to get off topic.

    Basically I have decided to run the M2 ATX for the computer and turn on/off of the amps. From what I can tell the M2 has plenty of featurs and will do what I need and more. Besides I am seriously reducing my power consumption and switching to a Mini ITX board and dumping all the unnecessary power goodies...fans, monitor etc onto another power supply. I have the space and batteries/alternator to do it. Even with running say the M2 and a little 60 watt that comes with a case, I will still be WAY under what I was running previously with the inverter.

    A pickup truck can do that. My civic is not able to do that, every watt counts for me!

    Agreed you have to pinch your watts, lol.

    Yes I am lucky in that respect I do have lots of space. It would be much more challenging in a Civic, or even my daily driver an escort. But with some careful planning on the electrical side of things I never had to worry too much about power consumption. I have extra batteries for tons of reserve capicity and an alternator that could power a mini-mall. But then of course that gets back to that whole small car thing finding somewhere to even put one more extra battery means your loosing space somewhere, not always an option.

    like mrbean_phillip mentioned, a newer system should use less power. a few places to start:

    core 2 duo + mobo that supports it (LGA775 socket i think)
    ddr2 ram
    5400 hdd (cheaper and less power i believe)
    pci-e graphics (replaced AGP a while ago)

    and then your preferred sound, wifi, etc. that shouldn't be that expensive and you should notice increased performance too. also, check out the 320W opus:

    Still Alive

    I wasn't aware this thread was still alive. Thanks for the input.

    After tons of reasearch and of course as things go with the hobby a little guesing, and trial and error I have long since already begun my rebuild with most of the parts you have mentioned. And no I did not choose a cheap soundcard being that is one of the most important things to me as apposed to graphics which are not, since I plan to do little to no gamming on the computer.

    Anyways things are going well, even though in another post I have had problems with my power supply, funny thing to it is the Opus 320, more than I needed for sure but anyways its been repaired as far as I know. I haven't had time to find out since winter is upon us here in Michigan and I have no time to play with it right now. Will know more when spring comes around.
