Will my power supply be sufficient for a 5070ti

Hey,

I just had my 5070ti arrive, my understanding is nvidia recommends a 750w psu which i have however a friend has expressed concerns that it wont be enough and may causd damage.

My power supply is the TX750M and my CPU is an i9-10900k.

Just wanna be sure before i get it all set up, dont want to cause any damage.
