ok, well i have a 300W inverter and i was going to use that. Then i see these DC-DC power supplys. That seems like alot better solution. I used one of those online calculators and it said 275 is the max it would ever use. I have like a 125W PSU in it right now (its an Emachines) and i dont wanna spend alot of money on parts that i cant carry over when i build a custom system just for my car. I just really wanna know what kinda route i should go. Stick with the inverter of go with DC-DC PSU. Im going to be getting a shutdown controller too for the computer. This one here:http://www.dashwerks.com/dw_dssc.php
edit** just found this HERE would that work for the PSU?
Any help would be appreciated.
I run my whole system (including monitor) out of a M1-Atx 90W psu

well im kinda streaching my limits on funds for all this. so i think im going to go with the inverter for now and ill get the OPUS when i have enough money.
Also does the OPUS have all the same features as that shutdown controller does?
If you get the money to spend, an OPUS really is worth the price. Of course, if you put a lot of work into it, you can get pretty much the same thing from an invertor. OPUS is just quicker/easier to set up. If you know what you're doing, you can get a setup just as good (though not as efficent) as an OPUS.

The Carnetix is designed to work with certain cases that have a power module in them (like an M1-ATX).
The Opus will work on any ATX motherboard (assuming the setup meets power limitations... You're not going to be powering your P4EE 3.0 with it!).
Why the big hype witht he Opus?
It's an all-in-one power solution, albeit with limited power output. It has a shutdown controller. It survives crank. It's got battery protection. It will start your PC when you turn the key. Opus Solutions stands behind their products and is very helpful (reading the forums confirms this).
