All ITX MBs I know of have an ATX style power connector, so unless yours is particulary odd, which I doubt, it'll work fine.
I have a lot of car audio experiance but I'm extreamly new to building computers (this is my first) My only question so far is will the opus 150w psu work with my Insight P4 ITX motherboard? The reason I ask is because the opus says its desgined for ATX but I want the largest amount of power in the easiest package possible. If this won't work then do you have suggestions? Thanks in advance.
Just a warning, you will get flamed if you ask questions like this, you need to , before submitting a question.
The connector won't be a problem, what you need to know is what power your system will draw.
Find out what each component draws in watts and then use a wattage calculator to find out if a 150w supply will handle it.
Thats what I thought. It looked the same but like I said I'm not sure about much of any of this stuff. Thanks.
We all have to start somewhere, a carputer may be a bit to much for you if you're new to this, you may want to start on something easier but don't let me put you off, have a good look around the forum and decide for yourself, if you need advise there will be a thread covering it somewhere here.
