How many ohms does an RTX 2080ti chip have on the NVVDD pins when it is not on the PCB?

I had a faulty graphics card, sometimes the power supply failed.
I desoldered this chip and replaced it with a good one that I had here from another board that I purchased just for parts.
Board before soldering the chip = power supply OK
Board with chip after reballing = Power does not start.

What strange defect is this?

as this chip on the old board was well powered.
