    Asus dual RX 480 short?

    I have an Asus dual RX 480

    I have taken resistance measurements of all the rails and cannot see a short but when in the pc and I press power button pc cuts off

    I have powered the pc up with just the 12v plug connected to the GPU and 12v is getting to the rails OK.

    There are no shorts on the PCIE connector, I cannot see any physical damage or find any other shorts.

    Are the resistance measurements ok. Is there anything else I can check

    Thanks for any help

      So the PSU shuts down ? I'd wouldn't power it up like that, without finding something that seems shorted. So u have a bench PSU ?

        check all the down side mosfets, you already removed one, if there is not shorted without the 12v (as your ohm measurands) maybe is one down side that is shorted. verify diode mode between emitter and gate
