    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?
