    M1 or M2???

    I started building a system about a year ago, and got sidetracked by life!

    Now i'm back in the game and all I have left is to choose power supply..
    I was looking at getting a M2 but keep reading about problems,so I was considering a M1.

    Here are my components so far, so you could give me your opinions

    VIA EPIA MII-12000
    512 Kingston DDR Hyper
    250 gig Seagate Hd
    Usb Earthmate Gps
    Usb Linksys Bluetooth w/ external antenna
    4 port usb hub
    dvd/cd-r drive
    Gyration Usb Wireless Keyboard and mouse
    or Playstation 2 mini keyboard and touchpoint pointer.
    Xenarac 1020TSV - 10.2" VGA LCD Touchscreen Monitor
    I'm getting monitor tuesday

    I have a few choices laying around for wifi, haven't decided yet
    pci linksys wifi w/antenna, or pcmicia senao w/dual antenna, or orinoco w/external

    I'm sure i'm forgetting something else that might need power.

    I have a 2002 VW Jetta Tdi diesel. I also run a fuzz buster, and have a completely stock stereo.

    Here is the kicker, in the next few months, i'm converting the car to run on used vegetable oil, So there will be a few more components that will need power, so I don't want to overload the car.

    I'm seriously considering going with the M1 over the M2.
    Will the M1 be ok, or will I need M2?

    Please help me with some info.

    Thanks for the input guys.

    But what about the M2 frying mother boards and other problems, I was reading about on here?
    That scares me, I just want dependable power. I won't be able to afford another power supply and mobo if they go out, for quite a while.

    Would a M1 work sufficient for me, or do I really need a M2. I previously had made up my mind on a M2 and was going to order one, but I got on here and started reading and most people had problems with them, or weren't that impressed with it over the M1.

    Anyway keep the info coming!

    ive heard several stories about the m2 frying mobos as well and to me they are all stories of people putting too much demand on the m2. Ive went through allot of different power supplies and used several different power options and with my experience the m2 is the way to go. Just dont exceed the wattage that the m2 was designed for and you should not have any problems

    also i find it pretty interesting that you are converting your ride to run on used vegetable oil, have you considered getting a OBD II interface as well. You might be able to tweek your ECU to get better fuel economy or horse power. At the very least you can use your carpc to track information on how well your car performs on the vegetable oil versus regular diesel

    Considering the load froom all the components & accessories, I'd say the M1 wouldn't cut the mustard. The M2 is the better choice, I'd think.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Thanks guys this helps! You guys have turned me around. I guess I'll have to start looking for a M2 pretty soon, after I get the monitor.

    That was one of the things I forgot to mention, the odb II for my car is called a vag com, and I saw the road runner Vw skin had a button on the main menu. I will definatley have one of those running to usb. You can do alot to the Tdi with one of those, believe it or not there is no way to check transmission fluid level without one, it's all sealed. As far as mpg I get between 45 and 55 right now, I might could squeeze a little more out by tinkering.

    I was planning on logging and comparing the difference in data between diesel, biodiesel, and used veg oil. I thinking I might be losing 1mpg using B100 biodiesel that i'm using right now. I'm hoping to have the conversion and carputer done to the jetta in the next few months, because I have to show it at the nearby college for earth day, along with my converted mercedes and waste oil collection trailer.

    I get the screen tommorow and I guess I will grab a M2 in a few weeks when I get a little more $$ to spare.

    Thanks

    Well I talied up my usage with a calculator and it looks like I will be running around 140 or more, I'm sure there are other things I have forgotten to count and I'm sure I will add more stuff later as well, so 160 is really close. I just don't want to overload it and blow the mobo.

    I really didn't think I would need that much power. So now I'm looking at the OPUS 250W Intelligent, I didn't realize it would work with my epia. Would I be safer getting it? I know I will end up adding more stuff later, so what are your opinions between the opus and M2.

    I'm down to this final piece and just want to do it right!
    Thanks again!

    You're looking at total wattage, rather than calculating the wattage draw from the three seperate rails.
    I firmly believe that the M2ATX will power your system with no problems whatsoever.

    Granted, the 250w Opus unit will, too, as well as leave room to spare. The DSATX would power it, as well.

    It's all a matter of how much money you want to spend, but the Opus and DSATX are really overkill for your setup. Hell, the DSATX is probably overkill for my setup.
