Thanks Red GTi VR6,
I will go with you and DarquePervert recommended to powering my Liliput.
I'm still not quiet understand many things, being new to the car audio and the car electrical thing.
Here is my updated daigram, it might help some other newbies out there.
are those USB hubs pulling power from anywhere or are they relying on the single USB line to provide power for everything?
I didn't power my Liliput directly off my PSU because I didn't want to load down the power supply. Instead I used the egg shaped regulator however I used the PSU to trigger a relay to turn power on and off to the egg shaped invertor.
This way, my montior turns on and off with the computer, not just the car, but is not directly powered by the PSU. Just another way to do it.
Added: Nice diagrams. good work.
They are relying on the two USB from motherboard. I already have two USB hubs which don't need PSU to power them lying around. So I was thinking of using them. Do you think I should get one of thoes that need PSU?Quote:

Thanks for sharing your method. :) This could be useful info for me and other newbies. I still don't know much about relay, but it is very useful indeed.Quote:

Just because a USB hub doesn't have external power doesn't mean it can power everything you plug into it.
Only so much current is carried on a single USB line.
If you plug one thing into that hub that requires all of the current that a single USB line can provide, then what happens when you plug the next piece in that needs just a little power?
That's where the powered USB hubs come into play.
Electricity isn't some magically generated thing, you have to provide it when it's needed otherwise things won't work correctly.
Most of the items you have listed don't appear to be very power hungry, and if they are they will probably have their own power adapter (USB sound card and DVD burner for examples).
Just keep it in mind if you start to run into issues with things not working.
Here you go..I modified this picture taken from www.the12volt.com
This is how I have mine wired up just from reference.

85 being the striped side (+) and 86 ground, so when the relay shuts down wont hurt your psu electronics.
You see, because the relay is a coil it will save some energy in itself and then it will reverse when shut off, this energy can reach up to 200v and a diode will prevent energy from returning to its source.
