    Non-opus solutions to power a micro ATx board and still offer everything Opus does???

    I have been searching for a long time. But I can't actually figure out if anyone has had as much luck with and Inverter, Regulator, Controller setup as most people do with Opus. Not only are the OPus' so much money, but I've been reading that, considerign they are primarily for Mini-Itx boards, that the Opus-150 might not even be suffice for a basic carputer w/GPS, DVD, SoundCard, etc.

    Personally im running a coleman inverter like TheCarPCStore.com sells.



    Then I plan on buying there CarPC Pro ver.2.4 which looks very hefty on features.



    You can check them out at TheCarPcStore.com

    Ive looked over and looked over again and again but it doesnt seem that the Opus does everything that the above shutdown controller does. Than plus the fact that I allready have a inverter has swayed me towards staying with the inverter/shutdown controller setup.

    Well a few people use the opus to power P4 2.4ghz systems - it is a good little PSU. Much better than a 150W mains PSU.

    If you need more power and to save money look at this: Mastero MK-4.5 250w 12v DC-DC ATX PSU + SDC

    I am not a big fan of inverters as i they are inefficent, electrically noisy and i don't like the idea of having 300-1000W of 230V in my car waiting for water.

    Do you think it would be good enough to power a Asus A7N8X-VM w/ say a mobile XP 2500+, with a Laptop HDD, GPS, TV Tuner, Liliput And a few other small things. ALso, I'll be doing some research on what a Powered USB hub is, I maybe using one of those too?

    Edit. I get it, the externally powered USB hub is wired directly to your car so you can save on the power from say an opus. I'll get one of those too.

    I think so. Your only problem maybe your USB devices. A powered usb hub is just a multi-port usb hub that uses an external power supply for amplifing the USB signal. You probally need one according to Opus for more than 3 usb devices that require power.

    But you are happy with your inverter and the Pro 2.4 when you get it. Maybe I'll go that route instead. The Opus is really quite expensive and like you said, what if I fall short with USB devices and all and only 150w?

    According to Opus if you use the powered usb hub, like this HERE ...



    The problem obviously is how to power the USB hub. If you take away the inverter from the equation then that changes the powering issue. Some have said you could use the Opus to power by splicing the wire but i dont know anything about this. I personally havent done much research on that because I wasnt willing to fork over $200 initially and the startup/shutdown controllers seemed to have way more options. People will go back and forth all day on this issue but personally i'm sticking to what works. If it aint broke, dont fix it type of thing.

    Some things i have seen people complain about the inverter power solution:

    1. Electrical noise in your speakers. (I havent experienced this except once when my audio jack was loose. Then again im using pc speakers until i get an amp (no headunit install).

    2. Uneffecient. (People say that intake to output ratio on inverters is worse. It probaly is but i'm not having any problems with or my battery as of now. Plus i'll be running amps, so it the wiring had to be done anyways.)

    3. Noise. (Inverters depending on size will have either one or more fans. Could be noisy if in the cabin but in my trunk at least i dont hear anything.)

    4. Wont survive crank (some may not, but my coleman has been surviving crank every morning. Might have something to do with the fact i'm running 5gauge wiring also.)

    That's just what i could think of right now. I am by no means an expert and I dont sell inverters (maybe in the future) but this setup is working for me so i'm sticking with it.
