    Thanks very much Robert, it's clear for me now, this is a good PSU to go.

    Do you have some experience with DSX12VD from Mpegbox which is 16USD more expensive ?

    Sorry, no, I never seen that supply before. I'm a newbie myself, only have 1 year of carpc experience.

    Beside a 12V dc supply motherboard, now I succeeded to source another one with atx power connector which I like more, I already have an M3-ATX 125 Watts (150watt peak) PSU, the problem is that I need 150-160W. Also I have a picoPSU-160-XT, 160W / 200 Watt peak a nice small solution which I don't want to use in a combination with an invertor and a brick to power the carpc. Does anybody here used this one - picoPSU-160-XT - in conjunction with a DCDC-USB-200 psu, and to control the carpc MB -power on, power off- from the DCDC-USB200, could this combination be feasible - powering the carpc with picoPSU-160-XT and control it by the DCDC-USB200 in the same time supplying the picoPSU-160-XT.
    It's just an idea for a small solution, I don't have yet the DCDC-USB200 to test this idea, and yes I know that instead using this combination of two PSU-s there is a compact all in one solution M4-ATX, 250w but I heard it's a very noisy PSU and also with big dimensions .

    Thanks in advance for any comments/experience on this topic.

    If you want big then go with the dsatx, http://store.mp3car.com/Mp3Car_DSATX_p/pwr-023.htm it has plugins for RR and CF and hopefully Driveline to monitor via the brainstem addon. If you just want turn on/off then I would get this http://store.mp3car.com/Startup_Shut...llers_s/80.htm Stay away from the m4 unless you like to diagnose noise in your system. See mickz's post on that subject (very eye opening) SNO

    Thanks SNO.
    I heard only good thing about DSATX, but my MB has a 24pins EATX connector , the DSATX PSU has a 20pins ATX connector, and it's bigger than this combination picoPSU-160-XT with DCDC-USB200 if possible to control the MB from DCDC-USB

    Any opinions on this?

    I think you could do it using your choices. I think the only way would be to set in your bios to have the computer restart after power failure. That way you could wire your usb-dcdc using ignition wire to turn on which would send 12v to the pico since it only has 12v and ground wires. Using the pico is suppose to have a power button connected to mainboard to turn on power since it is getting 12v from brick normally. In my daily driver I use a power button, I prefer to startup and shutdown as needed but It all stays powered if I turn ignition off to fuel up or short stops under 2 hours. Good luck SNO

    unearthing an old thread here. I plan to use a NUC carpc and need this DCDC USB thing. And I also need to wake up my amp. I'm using an M2-ATX and this has the amp remote line. I also need 2 12V outputs to power the screen and the microphone + a 5v output to power a usb hub. I don't want to have a multitude of PSUs. So far the M2-ATX is doing the job. Will the DCDC200 perfom similar according to your experience?

    Morning all...
    I figured this thread would be a good one to bump as it has a few DCDC-USB users here.

    I'm currently looking at the DCDC-USB-200 for my Intel NUC based PC. It'll take anywhere from 12-19v input and has a header on the board for a power button (the board is in the case with a button, but has an additional header...)

    Anyway, what's the quality like on the DCDC-USB-200 supplies? I was looking at the Carnetix 1290, 1900, etc... but 1) it's more PSU than I need and 2) there seem to be lots of complaints (and probably lots of happy users who don't post raves).

    Thanks for any input!

    I have 2 the smaller 120watt version Intelligent DC-DC Converters, and they each have over a year of uptime so far. No glitches, no dead battery, they just seem to work reliably for me.

    They seem like no frills, straight to the point power supplies that happen to have some nice customization options. Have you played with the USB settings/software much?
