    The mosfet can be shorted too, all those 3 pins (6,7,8) go through low ohm resistors to the mosfet.
    Or are you confused with pins (8,9,10)?

      Nice catch

      I have noticed this yesterday but seems like my edit didn't go through.

      The shorted pins are:
      10 - pfcOK (5 ohms to GND)
      8 - DRV (1.2 ohms to GND)
      7 - GND

      The MOSFET isn't shorted, I have desoldered and tested it before.

        The IC has finally arrived and I had some time to replace it.

        The results are amazing, the PSU now works perfectly and even the PS4 starts with it. It displays an image mentioning that it could not find the storage. The HDD is busted (because of the same fall that damaged the PSU), not even my PC recognizes it.

        Thanks for the help guys, I could not done it wothout you!

              Hello, I have a power supply PS4 PRO model ADP-300FR.
              The part around the fet is gone, I'm wondering if anyone has a picture of this part of the power supply to see the resistor R99 and diode D63 markings?
              Thanks a lot.
