    power questions

    Ok i have been researching putting a computer in my car and i have a few questions. I have a micro-atx mobo with a P3 1.0 ghz and i need to know how to power it. I have a big power inverter that i can use but is there any way i will be able to get my computer to hibernate when i shut my car off and wake up when i start my car? or will i need a opus dc-dc to be able to do this? also if using a power inverter will this power inverter work with my mobo/cpu? http://cgi.ebay.com/ws/eBayISAPI.dll...18463&tc=photo
    any other suggestions or tips would be very helpful because just looking online i can't find many answers to my questions.

    Ok im going to scrap the inverter for now because i want it to be able to turn on right when i turn my car on and i want it to hibernate when i shut my car off like the opus. i just dont want to spend $200. My question is will this power supply work? http://www.mini-box.com/s.nl/c.ACCT1...it.A/id.300/.f

    Yes, it will power it, though it won't control shut down etc. You would need to add an ITPS. If it were me I'd get rid of the 3ghz p4, and use something like a 2.4 / 2.8 celeron (use less power), and then use the extra cash to buy an Opus 150w. That will do everything you want

    well thanks for the reply but im going to be running a 1.0 ghz Pentium 3. i think im going to get a power supply and inverter and buy this http://carpc.kyferez.com/ , the carpc ez- the simple atx power controller. Just have to figure out how it works. but i think it will work for what i need. Correct me if i'm wrong

    Eh, that's ridiculous. $70 for a shutdown controller is too much. Buy and inverter, a few relays, and you're set. My shutdown controls were all done by me with 2 relays and a cube timer. Cost you say?? $25. The most expensive was the cube timer, $20. Cube timer, what it does is when it gets power, it closes a switch for 5 seconds or less, defined by a resistor, and then opens the switch, thus imitating a power button push. Set your win install to hibernate on power button push, and you're set. Hook it all together and you have a power controller. Both relays hook to your power to your inverter. One relay controlled by your ACC on your ignition, the other is controlled by your computer PS. So if you turn off your key, your computer keeps the inverter on until it shuts down and kills power. Viola!

    All the things that make that shutdown controller special that you wanna buy, the EZ or whatever, doesn't matter if you buy a cheap inverter. It says it will keep your computer on and blah blah blah, but not if your inverter cannot survive crank. Either way, you're gonna be spending about as much money as you would an Opus if you want a shutdown controller and an inverter that survives crank...

    So, save money, buy cheap inverter, build controller, or spend money, get opus, be happy.

    Yup, another good way to go. This cuts out my $20 cube timer.
