  • How much wattage will I need?

    I'm a little concerned after doing a bit of reading on here and hearing a few people claim that the 200 watt dc-dc PSUs actually only put out something liek 60 watts. This is the PSU that I have purchased to replace my PW-70a:

    http://www.mini-box.com/s.nl/c.ACCT1...it.A/id.300/.f



    I will be running the following (at most)

    M12000 mobo
    8" Xenarc VGA touch screen (USB = 1)
    200gb 7200 rpm full size Seagate Barracuda hard drive
    Panasonic CD-RW/DVD slot load rom in USB case (requires a 5v lead - can't I just get this off of the PSU? like the unused floppy plug?) (USB = 2)
    XM PCR (USB = 3)
    GPS (USB = 4)
    Audigy 2 ZS Notebook sound car (PCMCIA)
    Probably a wireless reciever for a wireless keyboard (USB = 5)

    So I will probably end up having to use a USB hub of some type as well (prefer it to not require an external 120V plug....)

    Does anyone have any experience with this PSU? Do you think that it will work for what I am going to be doing?

    I want to try and stay away from the inverter this time around. I know some people say that they can't hear any noise through their system but this is not going to be your typical MP3 car stereo system either. It's just one more thing to have to worry about wiring up and finding a place for that I'd prefer to to not have to worry about if at all possible....

    Any input would be greatly appreciated!

    (EDIT: would this be enough power for my set-up? http://www.mini-box.com/s.nl/sc.8/ca...it.A/id.356/.f

    I like the fact that it's all in one but I'm not sure about 90 watts being enough?)

    When I first built the carputer I incorporated that psu into the config, and also wasted money on the ITPS, which I was hoping to be able to control the startup/shutdown. I ran into some odd problems, eventually blew up the PW-200, and am now quite happy with the Opus 150W. (See this thread for details http://www.mp3car.com/vbulletin/showthread.php?t=38384)

    The problems I experienced could have been because of my not wiring directly to the battery, but nevertheless, I still had to turn it on and off manually because the ITPS was failure.

    Also, one of the things I've noticed, is the difference in the gauge of the power wires between the PW200M and the OPUS: PW200M like 16(?) ga, vs Opus 12(?) ga - I'm not certain of the diameter, but the Opus wire is a LOT thicker.

    The Opus may be more expensive, but it is well worth it. If I'd just got the Opus right off the bat, I would have saved myself a bunch of time, aggravation, and money. Just my experience.

      Oh - and I believe the PW200 also only regulates voltage within +/-15%... so what's that work out to.. 12 * 0.15 = 1.8v?

        what about that other PSU and controller that I listed?

        the M1-ATX?

        I still have the ITPS from a LONG time ago and it still works....but I'm ready to move onto the newer technology that's out there right now...=]

          The M1-ATX is fairly new out on the market. Sorry, I have no experience with it. I remember there was a thread around here a short while ago, but I see you already discovered it.

            yeah - already found just about the only thread that talks about it....maybe I'll start a new one to see if I can get a little more responses?

            worth a try
