    Exclamation Manual Power-On CarPC setup Diagram!

    Hey guys, what do you think of my setup?

    This is a manual turn on/off carpc setup.

    I was hoping tho, that someone would help me with the thickness of the wires from the distro-blocks to the relay, amps, etc.

    I've calculated my carpc power consumption and it apparently will have a peak of 200W. The carpcstore calc says that the minimum continuous rms power should be half of the peak.does this mean i would be ok with just a 150w psu?

    Anyone have any other suggestions?

    thanks!

    Why don't you lose the inverter and relays and crap and get an Opus 150w DC PSU?
    Then you get the benefit of not having to press a button to have the PC come on.
    Have you looked in the FAQ yet?
    How about the Wiki?

    for 2 reasons.

    1) its more expensive
    2) i want it to be manual for now. I can upgrade to auto-power later on if i want to.

    Can you answer my first post?

    Thanks!

    Only if I can read what the hell on the diagram.

    Seriously, if you thinking about saving money, go with DC-DV PSU. In the long run, you will be glad you spend more to begin with. I did use inverter for 6 months before switch to DC-DC. It took me that long cuz that is how long it took me to build the Sproggy.

    Manual control or automatic is just a mater of putting a ON/OFF switch between car's ACC and the PSU/Inverter remote turn on wire.

    The Opus 150w should power that setup with no problems. It's pretty comparable to my setup... I have the 35w version of the Athlon XP-M 2400+ in a Shuttle SN41G2.
    Also, the Opus 150w isn't the only DC-DC power supply. There are DC-DC ATX power supplies that will give you up to 250w... Not all have the bells and whisltes like shutdown controller, crank survival, battery saving, etc., so read specs carefully.

    Some other choices: M2-ATX (rated at 160w), DSATX (rated at 220w), KeyPower (rated at 250w)
    I'm likely going to use the DSATX for it's smaller size and higher power rating, so that I can upgrade the PC later on or add more devices as I wish.
