Will my current PSU work with a 5080?

so I currently have a AMD Ryzen 7 7800X3D, Zotac GAMING Trinity GeForce RTX 4070 Ti SUPER, and a be quiet! Pure Power 12 M 750 W 80+ Gold Certified Fully Modular ATX Power Supply

i know a 850w min is recommended but this PSU is not old, so I don’t wanna buy another if it’s not entirely necessary? Is it doable? Or should I cough up the cash for another one?
