  • Choices of DC-DC PSU with >= 180W

    Hello,

    I checked the FAQ section about ho to choose a power supply however the info seems a bit old. I'm looking for DC-to-DC PSU and found the following with higher output:

    1. OPUS 320W/250W DC-DC ATX/BTX
    2. Carnetix CNX-P2140 180W
    3. DSATX 220W

    Can someone share their experience with these or pros/cons on these? Really appreciate any input

    You really should search the forum for this sort of information. There are many readers and user experiences to be found.

    I, myself, use a DSATX and am thoroughly happy with it. If you get one, don't be cheap. Get the brainstem.
    Have you looked in the FAQ yet?
    How about the Wiki?

      It seems that DSATX has featured some command line interface to allow user tuning, but in reality what's the chance of using it? Also, I can't seem to find the website for DSATX comapre to OPUS and Carnetix, does mp3.com make it?

        I have the DSATX as well. The only time I use the brainsterm is to troubleshoot and or change the configuration which is rarely but it come handy.
        The PSU is designed and made by a fellow member here.
        So far no complain about the PSU and/or support from Jeff.
        If you wonder, here is the site http://mpegbox.net/dsatx.html. There are many places selling it.
        FYI, the Carnetic is just a regulator while the other 2 (or 3) is a PSU.

          What about "powerstream" psu ?
          400Watt CarPC power supply for powerfull systems- thaks for Beta testers- it was perfect.

          Remember - AMD Athlon XP (socket A) powers from 5v rail in most times !

            So the definition of PSU = power supply + regulator?

              No, but the better DC-DC PSUs do their own regulation.

                  Then does the regulation provided by those DC-DC PSU good enough for most parts? Will adding a regulator benefit anything?

                    Considering the growing list of satisfied users in this thread, I'd say that it does...

                    No.
                    As I said, the all-in-one DC-DC power supplies do their own regulation.

                    Why on earth would you think that you might need a separate regulator?

                      Thanks for the clarification, I'm just wondering the use of regulator besides connecting a notebook. Most wiring diagram I found on the site has older type of PSU or regulator, with all these new models coming out, I just want to make sure how should I modify the diagram
