    Can a Carnetix CNX-P1290 90W power these three?

    I know this powers 2 devices, but can it be rigged up to power 3?

    1: Lilliput 7" screen
    2: Via Epi mobo
    3: 4 device USB powered hub?

    I want them to all trun on together you see?

    Thanks in advance!

    Yes it can.

    Use the 12V feed from the carnetix to power your screen and a suitable DC-DC ATX powerboard for the Epia motherboard.

    Then use the 5V feed for your USB powered hub.

    Thanks for this - I have a "12V 200W Epia MII "Plug In" Power Supply Board" on its way. Sorry for a moronic question but if the carnetix supplies power to the plug in board (via the female round power connector) does this not mean that the 12v line is already taken?

    Just tap into the 12 volt outputs before you wire them to your power supply.

    Easily. The Carnetix rocks and Mike provides GREAT support.

    Perfect - thanks. I hoped that this was the solution but just wanted to check before screwing it up

    Since I have your attention, Iam happy with the solution above to run the mobo and screen from the 12 v supply,and the usb hum from the 5v, but is there a way to also run another 4 way usb hub from the system or is this overload?

    I am just about to install the device in the car, I assume there is a pass through remote turn on cable for amps?

    Thanks

    markuskj,
    is there a way to also run another 4 way usb hub from the system or is this overload?
    As I'm sure you know, hubs don't draw much current....However, USB Devices CONNECTED to hubs can potentially draw lots of current... So the answer to your question is...it depends. What devices will you be powering? The total current available on the +5V output form the P1290 is 3 amps. This will easily power many small USB devices like keyboards, mice, GPS receivers, as well as a few larger devices. Power hungry devices like USB sound cards (ie Audigy 2NX), USB video cards, and some USBS WiFi devices can potentially draw quite a bit of current. You'll need to do a bit of homework on your specific config to see if you're within the 3 amps limit. If not, you can always add the CNX-P5V. It gives you another +5V/3amp output, doubling the +5V power available.

    I've posted some examples of my system devices HERE. The Audigy 2NX draws about .8 amps.
    I assume there is a pass through remote turn on cable for amps?
    There is a "remote" trigger for your amps called DLYON (delay ON) which has a 3 second delay before it enables your amps. This helps prevent speaker "thump".

    You may want download the Installation Manual from HERE.

    I hope this helps!
    MikeH
