    See above.

    Putting the regulation at the point of the load assures that the proper voltages are delivered to peripherals without the significant voltage drop associated with long runs or the need to use large guage wire to avoid those same drops.

    5V is the name of the game for most peripherals. Simple buck regulators that can output 2-3A would work for nearly all peripherals. A larger 5-10A supply might be more appropriate for a group of co-located devices. Proper sequencing of the power may be required for some applications to work properly but I think it's less of an issue than with what I was talking about before with the 12V supply and the M1-ATX.

    gosh im about to solder fifteen 12v, 2amp max regulators together to make a 30amp 12v regulator for my pw200... perhaps if i fail or become too lazy i can pick a couple of these up

    Or, you could use one 12v regulator and 2-3 beefy pass transistors. But hey, its your project.

    That's exactly what I did. I'm installing it in the car today. But I would have bought this had it been available at $50. Now if you want to combine it with your $42 shutdown controller and sell it to me at $70 I'll still bite . I'm a good beta tester!

    eh i never heard of these pass transistors, or beefy ones for that matter... cant say im much of an electronics genious

    if you care to elaborate, perhaps i can simplify my project...

    when would this dsx12v for $50 be available?

    Probably after enough people buy it at 70 and I'm able to get the volume up!

    Chances are you would have to add some kind of load balancing circuit for that which will up the cost and complexity. I got away without any of that with 13 of the 2A regulators and 6 capacitors. Running in my car now . But it definitely won't work below about 11V .

    Take a look at this: Increasing Regulator Current

    Planning on building one myself.

    Than Radioshack 2N3055 can be substituted for the "TIP2955" specified in the circuit.
