Thread: Some power issues, ignition and shutdown etc..

So i have this question,
I have bought myself a morex 80w psu with 12v and a simple earth on it. So my question is when i turn the ignition on, the psu gets 12v from battery and so does the cpu mother board. But the mother board has a power switch also and i need to push that to get the cpu to launch. So how would i be able to get it to auto start when i turn the ignition on? And how is it possible for the computer to shutdown itself (safe mode) when i turn the ignition off? (will say, i dont want the cpu to just die when i turn ignition off)
help me out with my issues please...
and yes i have read some faqs but im still a little stuck with my head :S
