    Which inverter?

    Hi all... New to carpc's and to this forum but been lurkin' for a while to get tips. Here's my story.

    Changed my car to a FTO couple of weeks ago and decided I wanted a carputer. I built the pc using a microATX case, Asrock microATX mb, AthlonXP2400, 256m ddr2100, 80gig 3 1/2" HD, full size cdrom,7" Lilliput touchscreen, serial GPS mouse. I know a lot of you will say I made some bad choices but I was working to a budget, space wasn't an issue and I wanted to be able to add stuff easily in the future. For power I bought a snap-on 200w power supply, ITPS, and a shutdown controller (the one with the 3 adjustable pots). I got these because a local guy was selling them so it saved me from having to send away and also I think the Opus is way overpriced, I know that comment will pi$$ some of you off but I'm sure that they cost no more than a good quality desktop power supply to make and yet I paid less than half the amount of an Opus for my Thermaltake.

    Got the pc built and loaded up with software and installed it all into the car, loosely. Soon as I powered up the motherboard died. Okay, off to buy a replacement motherboard, same model by Asrock, powered up and after a few mins motherboard died in the same way. I guess the psu or the ITPS is killing my motherboards so they get thrown aside. I bought a Abit microATX motherboard next and decided to try the Inverter route, I have a cheap 150w inverter just to test before I buy a decent one. Today I put the pc in the car again and it powered up great with the inverter and ran sweet, but after 10 mins or so the inverter switched off, not enough power I guess, at least I know it works though.

    The question I have is, should I go for a 150w true sine wave inverter (79.95) or a 600w modified sine wave inverter (69.95) and try to mod my power supply? Also, can I use the shutdown controller with the inverter?

    Sorry this went on for so long...

    Cheers... Rob.

    I don't want to sound rude and I'm greatful for any REAL help, but please, if you have no answer or info for my particular situation then don't just tell me to search, it really doesn't help.

    I can see why the guy asking about th PW-70 got so ****ed off, though I won't stoop to his level as I'm British so politeness is bred into me.

    I like inverters.

    Plus: I posted this deal last week. 30 shipped free from amazon. Sounds like its pretty good. Some people have huge noise problems with inverters, not me though.

    I think to fix your original problem, you need to invest in a digital multimeter and firstly check your vehicles battery voltage when running and when off and then check that you got your power sorted out, to have that number of mobo failures is quite impressive, I had to work real hard to blow my mobo !
    once you got your voltmeter, do some tests, post a schematic of your component layout and let us give some good advice from there on

    true sine wave are meant to be better,but that one you have seen looks if anything, to cheap.

    This might be a really dumb question but i am connecting my inverter to the battery and i need to know which wire is power and which is ground. Black/white and Black are the options.

    Ok... Went to Maplin and the ONLY inverter they have in stock at any of their stores is the 150w true sine one for 79.95. The guy who served me said I can get a refund if it doesn't suit my needs so I bought it, will give it a try and post results so you all know if it's a viable option.

    I too was impressed that I managed to kill two mobos, they WERE Asrock though.

    Will a power supply pull it's rated power, e.g. 200w, or will it pull the power it is using, i.e. the total sum of components in the pc, e.g. 130w or something? Hope that makes sense.

    Thanks for you advice so far...

    Rob.
