How do I know if my power supply will support my new GPU?

I plan to upgrade my PC as soon as my salary comes in at the end of the month. I currently have a 500W power supply and an RTX 3060. I’d like to get a 4070 Ti Super. Will my power supply handle it? If not, how can I find out? Is there any calculator? Is this information written in the graphics card description? What would be the most suitable power supply for this GPU model?
