    Question mobo grounding question...

    Ok, so I can see the need for grounding your mobo when you are using an inverter in the car to get power to the mobo; but what about when just using a dc-dc psu? Especially since the ATX plug has quite a few grounding wires....

    When using the inverter you are taking dc to ac then back to dc, which could cause a floating ground, right? Ok so when you have dc-dc that floating ground isn't an issue, right?

    so then would it be necessary to ground your mobo when using dc-dc??

    just something we've been pondering since the last install.....

    it is grounded through the wiring harness. i have an MII10000 with an Opus 150 and it isn't grounded other than connecting the black wire (off power supply which goes to ground)

    ok - so then a seperate ground isn't really needed when using Dc-Dc?

    cool, not that it's a big deal this time around, just something we had been wondering about for a while now

    thanks!
