  • Using two m2-atx's?

    I have searched but nothing has answered MY QUESTIONS?

    I have read many bad things about the m2-ATX. I have calculated the power consumption and itís around 140w max. My setup is from Pc club. http://www.pcclub.com/product_system...emno=UPG00071#

    My mother board is from biostar and my CPU is an INTEL CELERON 356 my hard drive is from my dell laptop. So that wonít use much power. And a DVD drive and a USB keyboard. Thatís all Iím going to be running off the PS. Will this work? And if it doesnít work could i buy another m2-ATX and wire them together?

    1) Likely
    2) No
    Gen 1: Pentium 3 1GHz - ATX - 2005
    Gen 2: Pentium M 1.6GHz - ITX - 2006
    Gen 3: Pentium M 2.0GHz - 5.25" SBC - 2007
    Gen 4: (coming soon: Core2 Duo - 3.5" SBC - 2009)
    ...it never ends

      Likely? what does that mean. NO what does that mean? I have read that you can wire two m2-ATX's together. I just can't find the post. Mybe i can buy another M2-ATX to power My harddrive and my DVD drive. That means that the first m2-ATX could run the MB and CPU and USB. or i could combine the PSU to supply more power to the system.

        Likely, meaning it's good that you don't have many accessories, but a Celeron D 356 is 86W according to intel's processorfinder, which is kinda on the high side. There's a good chance it will work, but you're right on the edge, I think.

        No, meaning you can't connect two together. You can power separate things with two PSUs (even desktop PSUs, it's not M2-ATX specific), but you can't join the PSUs to act like one larger PSU.

            Ok, so now i know that i can use the first m2-ATX to run the motherboard, CPU and USB devices. the HD and DVD drive off the second M2-Atx. Is there any other things that run off of the 12 volt rail? Even though this is an option would it be better to return my m2-ATX and buy a DSATX. not much difference in price.

              Most people also run the LCD screen off the 12V rail as well.
              Typical Load: 0.8 ~ 1.0A

                I was searching this forum and found that my CPU which is a Intel Celeron 356 is rated at 86 watts. does this include the mother board? if it does then it should work with the m2-ATX. I'm using a DDR2 512 memory, 2.5" HD, USB keyboard & mouse ball and dvd drive. later on i will add a GPS antenna. If i use two M2-ATX's which M2-ATX will power what?

                  86W / 12V = 7.2A
                  Just the CPU alone would require 90% of M2's 12V rail.

                  Don't do it, even with two PSUs.

                  Read this instead.

                    so i should send back the M2-ATX and buy the DSATX? will that power what i am running with room to upgrade? By the way i am using a 17" inch wide screen desktop screen. don't ask why and i know its crazy, but thats what i am doing. is there a way to hook up my screen to a M2-ATX?

                      the DS-ATX Opus250 or Opus320.

                      And there is no way in hell you are going to be able to power that monitor off of any DC-DC PSU I know of.

                      Those monitors are beasts, and usually require screwy power. A lot of the ones I have installed are 19v inputs, some are 12v inputs, and some are 15v inputs. But to get enough current at 12v, regular PSU's wont work.

                        Is mp3car good with returns? another question. would i want to run a M2-ATX plus a DS-ATX. My cpu is rated at 86 + 25 for mother board + DVD Drive 25 + Hdd 2.5"= 5 + DDR2 512 memory= 7.5 =146 all on the 12v rail? or do some of these spread their Watts over 12,5,3.3 rails? and USB key/mouse. If i keep the M2-Atx i could run everything but the CPU and motherboard off of it.
