There is none.
You have two options:
1 - Use an inverter with a startup/shutdown controller
2 - Use different hardware that draws less power.
I have a Carputer with Asus P8H67-I DELUXE and i7... etc.
I need a PSU that will work with ignition and provide at least 850 wat. I searched, but did not find a way.
Please,, any idea
I just bought that board. If i were you i would ditch the i7 and opt for an i3.
Even with an i7 i don't think you'll need anywhere near 850w.
The Opus 320 would certainly work for you, but i am planning that board with an i3 3.1ghz (should be here today) with a M4-ATX (250W) 3.5" Hard drive and many USB devices.
Note my Zotac H55-ITX-C-E worked fine on the M4-ATX with a 3.2ghz core i3. I think your grossly overestimated your power consumtion. I would do the math again on one of those power estimator websites
Remember this is a Carpc not a desktop system. You need to consider power consumtion in every aspect of your build. The core i3 will be far more processing power than you will need in carpc over the next 3 years (estimated product life) many people are more than happy with the Atom based processors.

Actually, I think you can get it up to 850W Let's take a look!
So let's say you are using Core i7-950. It can use up to 233W at 100% without OC (according to bit-tech.net)
Mobo eats around 120W
Since he's using Core i7, I can only assume he's also using a high-end video card. For instnace, GeForce GTX 570 eats around 330W under load.
Hey we already got to 680W! Add up some peripherals, and we'll climb up to 700W no problem. And power supplies don't like to be pushed to 100% load, so 850W isn't unreasonable for that caliber of a PC. What is unreasonable is that caliber PC in a Mini-ITX formfactor, and even more unreasonable to put it in the car!
Sorry, almatrodi, you might want to rethink this project. What are you trying to accomplish?

Thanks to all
What I have right now is:
- Asus P8H67-I DELUXE 350W
- Intel Core i7-2600K Processor 3.4GHz 8 MB Cache Socket LGA1155
- 8GB DDR3
- Toshiba Slot-Loading Portable SuperMulti Drive PA3845U-1DV2
- Lexar Media Inc Crucial 128 GB m4 SATA 6Gb/s 2.5-Inch Solid State Drive CT128M4SSD2
- Holux Mini Smart Mouse Type GPS Receiver GR-213U
- Some USB powered items, such as USB Flash, USB HDD, iPhone, HD 7 ...etc
About the VGA card, I think the built in one is enough for me
How much Watts do you think it will be enough for this system?, and from where can I get it?
I visited http://support.asus.com/PowerSupply.aspx?SLanguage=en and see. It gave me 350W, but in motherboard's specification, to make it work effectively at least 350W
I ran two different i3 motherboards in the last year using an M2-ATX without any problems. I'm currently running a quad-core i5 sandy bridge with the same 2 year old M2-ATX I've had in my truck from day 1. No problems...works like a champ. And I suspect that the i5 is sufficently powerful enough to handle any reasonable in-car tasks.
Sometimes more is just....more, not better.
what are you planning on doing with this pc?
My OLD 2001 Mitsubishi Eclipse GT:
"The Project That Never Ended, until it did"
next project? subaru brz
I was thinking of fast boot and response, I used i5 with notebook and it was awful, but I think I made a mistake
What do you suggest, use it as home desktop and buy another low voltage one?
right now, I am thinking of buying a 500W like http://www.alibaba.com/product-gs/43...Converter.html , and roll the dice
Well if you want to encode HD videos while playing dx11 games at max then yes, desktop it is. I would never put a system like that in my car with the chance someone steals it.
