    Need some extra advice on wiring my PSU to my car and CarPC

    Alright, I have done the calculations and I think I have this figured out... but I am new around here and I have never built a carPC so I am just unsure.


    I am going to be running a system with the following parts:

    1. Intel BOXD945GCLF2D Intel Atom processor 330 Intel 945GC Mini ITX Motherboard/CPU Combo.

    2. 2 Normal speed HDD (80GB + 160GB).

    3. 1 Stick 2GB DDR2 RAM (667).

    4. Lilliput 7" Touchscreen.

    I have done the calculations with extra things included incase I want to add on and I came up with 90 Watts for a Power Supply.

    I am planning on going with the M2-ATX 160W.

    My main question is will I need anything else to connect the car battery to the power supply and then the power supply to the motherboard? or will I have all the connectors?

    Just a side note. I will be installing an AMP for my speakers and the computer will output sound to the amp and then to the speakers... do I need to take this wattage into consideration for my PSU? or since it will be connected to the battery on its own will it be fine?



    thanks for all the help in advance! sorry for the newb questions!

    the m2 should include all the parts to connect it to the motherboard properly, but you will need to supply your own wire for connection to the battery.

    why not get it from the mp3car store, and help support the forums?

    for battery connection wiring, i like to recommend the amp wiring kits at walmart-- they are dirt cheap, decent quality, and will include almost everything you need for a install.

    for the amp wattage, you do not need to factor this into the power supply calculations unless you choose to power it off the m2. the power supply calc's are mainly to make sure that you do not overload the computer power supply.

    If I were to buy the M2-ATX I would probably purchase from mp3car, but I think I have changed my mind...

    I am looking at going with this 120W Opus, because I have heard that they are much better quality...

    Is there any way I can hook the computer up in-home once I have all the parts without buying a standard PSU?

    thanks,
