RX 6800XT nitro+ with a 600w PSU

Hi everyone, I just bought a RX 6800XT nitro+ second hand as an upgrade over my 1660ti. I did look up my system beforehand on a PSU calculator, but now that I have GPU I can see that it says 850w minimum on the box. (My bad for not looking it up before I bought it)

But I’d like to ask if it’s possible to run with my current setup, or if it’s recommended to upgrade my PSU as well?

Specs: (let me know if you need more)

CPU: i5-11600KF

GPU: RX 6800XT nitro+

PSU: Corsair SF600 80 plus platinum

Thanks in advance!
