Graphic card repair - SMD parts

[ltktomas]

Hello guys,
I have just got a graphic card (ASUS GTX1070) to repair.
Its owner managed to damage the bottom side of the card and now it freezes when under load.

This is probably caused by some SMD parts missing at the bottom side right next to power sensing.
I managed to get the same card so I would be able to compare what exactly is missing, but I'm not able to identify these two SMD parts:

1) SOT23 marked as WCJ (EQ97, Q503)
2) (most likely) SOT363 marked as K6ND2 (Q526 on PCB)

Does anyone have any idea what this could be?
