    Thumbs up 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?

    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?
