    3 CarPC setup in Mustang

    Hi friendly forum folk,
    I am installing three Power Bundle - Mobile Car Computer System $584.99 from the MP3.com store to install in my 07 Mustang.
    Why 3 car PC's?
    I need them, trust me.
    Anyway, I was wondering is there a special 2 battery/2 alternator setup I need to do to run three car PCs or can I do it with just one heavy duty top of the line 12volt battery and my stock alternator?

    Thank you in advance.

    You don't need 3, for anything. But go ahead since it's fun! Your car PCs aren't using very much power, and will not be an issue on the stock charging system.

    Thanks for the info dscustoms!
    You were right about the low power requirements of the motherboards. And it seems I have changed my setup a little.

    2 Power Bundle - Mobile Car Computer System CarPCs
    1 Normal desktop PC with a SOLID STATE drive and and specs similar/same as this:

    Video card: http://www.newegg.com/Product/Produc...82E16814102875

    mobo: http://www.newegg.com/Product/Produc...82E16813131659

    cpu: http://www.newegg.com/Product/Produc...82E16819103817

    And a 1000 Watt DC/AC Pure Sine Wave Inverter - 12V to power it: http://www.amazon.com/gp/product/B00...tomotive&psc=1

    Now my question is: Will I still be OK with a one battery setup with this new configuration?
    Thanks again for the help!

    My setup was originally supposed to use 7 computers (I drive an SUV with 6 passenger seats). In the end I went with a system with Dual-Core and 4GB of RAM for the Dual-Zone setup. For the individual computers I went with a single AMD Phenom X6 setup. It basically uses virtual machines and creates 6 different environments. Only issue I am having is assigning USB devices to each VM. If the devices are the same, like all my soundcards, it tries to install all of them on that specific VM. So in short, I have 2 computers creating 8 independent zones.

    I'll recommend again that you review the system specs. What are you planning to do with this? Are you planning on using a desktop power supply with that inverter? You would be better using a mobile DC-DC supply. If you are using a desktop supply, I'd get ONE supply and use it to power all three systems.

    Yeah, I'm puzzled by this, too. 2 computers in a Mustang is overkill because NO ONE wants to be riding in a back seat that small. 1 PC can easily handle two users, especially if one is driving (won't be able to utilize a whole lot, safely).

    3 Computers is your car doesn't even make sense. I really think you are overestimating your needs. I could be wrong, but I just don't see it.

    I agree, my Dual Zone PC is split into two areas, the driver (can only see driver based stuff), and the passengers (see only entertainment stuff). I am using a C2D with 4GB of RAM. I am also using onboard video and PCI based soundcard. I did this to save on power.

    Yes, review the system specs. I know for a fact that the graphics card you plan to use requires over 300 watts to operate. Plus 95 watts for the processor and any USB and other devices will add onto it too. No automotive PSU would be strong enough to use the setup. You would have to use an pure sine wave inverter and a desktop PSU. You will then have to figure out a way to automate the start up and shut down process. The way I am getting around it (my install requires a 550 watt PSU) is that the inverter is controlled by the OPUS 320 automotive PSU via relays. With that said, if the main pc is off, the second pc can not be turned on at all.

    You should really rethink your setup. Trust me, I have wasted tons of money on my install trying to work out all the bugs that goes with a multi pc based install.

    Yeah. I have near the exact same car in all but year and options I believe.

    Aside from the "seriously?" factor this brings to mind, even with kids involved for outfitting, as to your original question, our OEM alternators only do about 75amps at idle and absolute max is like 130. This is assuming the OEM one is in great working order, is working at that limit, and assuming you're not one of the many with one that has issues, or about to crap out completely... Then I'd expect to go through a battery per 6 months as a decent guess IMO with what you plan on.

    My current setup I consider massive overkill, even for a multi-monitor VM setup. I just wanted some future-proofing, no chance of a speed issue for video playback, and I like to cook bacon in my console from the heat generated...


    Opus 360 only...about 40mins is the max before risking flintstoning it home with this (engine left off). Even careful, my average is about a year and a half span for battery life now if I'm lucky. That's 1 PC, the stock factory "Faker 1000" amps, and a 300watt kenwood doing the normal speakers.

    If you're dead set on something like this, then you "might" be able to get away with it, but I would suggest something like a second battery with an isolator. FUBAR a spare, not the means to get home.

    Wow thanks guys!
    A lot of useful info!
    I need 3 Car PCs because I am the guy who made this:


    I NEED all these PCs to work to do various car functions of the new KITT.

    The Sine Wave/High End Desktop route is the way to go I think for my graphics intensive PC application.
    Then the other 2 mini ITX PCs can run off of there respected PSUs.
    That would work with a 1 battery/alternator setup right? The only difference in working with the Sine Wave Inverter would be I would just have to go to the trunk and start THAT computer manually right?

    OMFG...

    I want one. I still think a modern pc could handle that load, if you are using a good graphics card. That's ******* beautiful. I hope you aren't messing with us and using prerecorded sound board clips...

    OMFG did I say that enough? I need that in my Lexus, asap.

    Is this a product you are selling? KIRAD ? Have you been playing with this for years?

    It's freaking cool.
