    M2-ATX general questions (help)

    Im going to be buying one of these in the next day or two but have a few questions.

    1) After wiring it to the battery (have to get a car electrician to do it) does it connect to the ATX on my MB directly (Epia MKII 12000 & Travla C156) or will I need an adaptor?

    2) Will I need a seperate power supply for my Lilliput or can it connect and power that too?

    3)There was another question but I cant remember it!

    Answer to Question 1: No special adapter needed. The M2-ATX comes with a standard ATX connector that will plug right into your motherboard.

    Answer to Question 2: For powering your Lilliput, it's recommended that you use the M2 to power the screen. I cannot remember exactly what I did, but you use one of the 4-pin connectors to power the screen. This 4-pin connector is already connected to to the provided ATX connector that comes with the M2. I'm blanking on what I did with my Gain touchscreen, but I'm positive there's a sticky on it under the FAQ's section. Basically you're cutting both the 4-pin connector and the cig light adapter. You connect the positive wires and the ground wires together. But check the FAQ if you go this way.

    Your other option is to power the Lilliput with the a cig light adapter. But people recommend the M2-ATX route because the power source is "clean."

    I think he means the 4 pin molex connecters that you normally connect to yoru hard drives. There will be four wires
    Red - 5v
    Black - Ground
    Black - Ground
    Yellow - 12v.

    You want to use the yellow 12v wire and the ground next to it. You can either splice into the wire leaving the connector attached, cut the connector off full stop and solder onto that or get the male molex plug and, plug it into the female and go from there.

    I installed my carpc into my pet Kangaroo, mate.

    Yep that sounds right. I could not remember which color was 12V and which color was 5V.

    Make sure that you don't exceed the M2's current ratings on the 12V rail if you decide to use it to power your screen...overdrawing the M2 frequently results in catastrophe.

    Ok,..So after waiting God knows how long my M2 arrived yesterday - minus the instructions!
    A quick search on here brought up a link to the manual so all is not lost.

    Im assuming when I cut the Molex off I can connect the yellow 12v and black ground direct onto the live and ground off the Lilliput power supply (obviously Ill remove/cut the plug off the end first).

    ^^ Yep. That's how I've done mine. I cut the lilli wires just before the power filter (ie. removed it) and soldered the atx wires on there. If you pop open to power filter, you will be able to tell which wire is + and which is -.

    The screen only uses like 8W. That's .67 Amp's of Current.

    You will probably spend AT LEAST 2x what you initially budget for your CarPC Project!

    You screen will do fine when connected directly to your cars electrical system. I have been hooking up all me screens directly to the cars power and never had a problem yet. I have installed 6 different screens in my own cars. There are a lot of people with multiple screens and do no have them all hooked up to a DC regulator.
    Your choice though, M2ATX and M1ATX are both not too reliable though when you start coming close to its max power ouput. I would keep as little as possible plugged in to it.

    It all adds up quick when you start adding USB devices and CD/DVD drives. A DVD drive alone can consume up to 3 amps / 36watts. Just saying use caution.
