Hello,
I was planning to change used GPU waterblock, but found some physical flaws.
The GPU (1080 ti aorus WB) has the damaged ground pin (B4).
As far as I can see, there are else much more other ground pins on the gpu, which are ok.
Is it safe to use that gpu with one damaged ground pin?
Here is the extract from gpu first 11 pins specification and gpu photo as well.

My understanding is that as long as the ground pin on the other side of the connector is intact it should be ok.

Thanks to everyone!
So, the practical experiment brought some bad experience:
That GPU damaged the motherboard PCIE slot at system startup.
It seems the motherboard is out of work now.

So my personal recomendation:
Never plug GPU with damaged pins into your PCIE slot!
