So that should work right?
How do you find out how much load is on the opus power supply? I have a 90w one.

Yes. That's how most people power their LCD screens, except they use the yellow wire (+12v). |

Cool, now would it be safe to have 2 unpowered usb hubs linked together or is that not a good idea for the PS.

You'll have problems with the devices you plug into those unpowered hubs. Powered hubs are the way to go. |

Shouldn't be too much load unless you're overloading the PSU else where. |

I have gps and the touchscreen, hard drive. And then the cdrom will be attached usb. Then i am adding a usb card, oh and bluetooth. The 2nd hub will be for user port availble to driver or passenger in the car as well as a memory card reader.
Do you think that is too much? Most of the is low powered devices.
Thanks

What motherboard/cpu and what power supply are you using?
And hey... if the PSU can't supply enough, you can always get a opus point of load psu just for that line. |
