g2 650w

I am looking to buy a used 1080 TI and was wondering if my EVGA G2 650w going to be enough since that card seems to be overclocked out of the box. Will I be able to run that GPU with my CPU overclocked to 5ghz at >1.35v using the power supply? PC specs: CPU: i5 9600k Graphics card: Zotac GTX...
