    Question Seeking: 300watt, DC to DC, ATX, PS that will take 12 volt input from a Solar setup.

    I have a 12-volt solar system with batteries on my RV. I want to be able to run a mid-tower ATX system off of it without wasting the power to convert my DC to AC with an inverter, then back to DC again with a normal AC Power supply.

    No, I don't want a notebook, too many issues with that. And Micro-ATX or ITX is a little non-standard at this point, I want to stick with other components I can easily replace, hence normal ATX. (If I can't find an ATX i'll probably just invert, but I hate to)

    Anyone know of such a Power Supply?

    Thanks.

    Maestro may be able to help here. My only though was two opus 150W supplies, run the mb fans etc on one and the drives on the other.

    is it possible to get 300 watt from a reasonable sized solar cell in the first place ?

    Wouldnt the size of the cell have to be larger than the roof of most vehicles ?

    'scuse my ignorance if I am a bit in the dark so to say,

    I run a 170w 12vDC/DC ATX power supply that drives a fulle size ATX mobo, AMD XP processor, GeForce 4 card, 7200 rpm drive, DVD rom, gps, DeltaDash, usb hubs, wireless mouse and griffin powermate and it survives a crank, cant think why you would need 300w just my 0.000000002 cents with the exchange rate the way it is its not worth much.....but to me

    MicroATX is just as standard as regular ATX at this point why do you think its not? I also agree with SAScooby, why do you think you need 300 watts??? ATX motherboards shouldn't consume more power then a MicroATX motherboard either, which shouldn't be more then 150watts unless your running multiple drives or something really extreme. My anthlon 2000+, geforce 4, and 7200 rpm drive only consume 100 watts at peak usage.

    300W running on Solar, that is IMPOSSIBLE on any vehicle on the road today.
    MicroATX and ATX are every much the same. The only thing I see that are different between the 2 are size, and onboard sound, graphic, expansion slot.

    I think 300w is overkill. I'm waiting for Mastero to come out with the MK-4.5 to see how it runs and how much it costs. Most likely I'll be going with the MK-4, which I think will be plenty of power.

    Orbit micro have a 250W ATX 12V DC-DC PSU.

    I have one and it's ok, standard ATX size.

    Not possible? The man did say he has batteries in his system.

    The biggest DC-DC ATX PSU that I have seen is a 250W. Made by Keypower, and sometimes rebranded by others like Orbit.

    Yeah, 250 watts would probably do it. Where is this one sold?

    I've just got alot of hardware in this system, Radeon 9800, 3 Hard Drives, video capture card, DVD-RW, heh.

    As for the solar system it's running 2000 watts of solar panels, a wind turbine and if I need it an unleaded generator. So there aren't many situations I can't handle.

    (I mean I have a LaserJet 6p in the mix, as well as when I kick on the AC it has a huge draw. The generator is linked to the voltage regulating system in the RV, so it turns on automatically when situations demand. I wish I knew more about power.. learning slowly :P)
