  • Finding a 5v line...

    Current setup as follows;

    P1900 - Main line feeding a M2 ATX in dumb mode powering a Dual Core Mini ATX motherboard.

    P1900 - Optional line running 12v to power touchscreen.


    Somehow I need a 5v feed to directly power a USB hub up front in the car. I can't use the optional line on the P1900 as this is powering my touchscreen. The M2 as I can see it has no provision for a secondary output at 5v.

    Any ideas on how to do this? The USB hub will power;

    Capture Device, Wideband logging, MUTII logging, touchscreen controls, card reader, and a secondary unpowered USB hub. (Used for USB memory sticks)

    Plugging all these devices into a unpowered hub kept freaking out the MB previously, and my bodged powered hub (12V to 5v cigarette adaptor) decided to melt yesterday.

    Thanks guys

    Discovered the P5V for the 1900.

    Job done.

      there was no need to buy the P5V... the M2 has 12v, 5v and 3.3v output rails. the red wire(s) in the molex/ATX harness is the 5v rail.

      and why are you using the P1900 at all? the M2 is designed as a primary power supply. it provides regulated power and has a built-in SSC.
