It is not clear to me if you now have a i7-12700K which is wonderful, or if you need to buy a cpu in which case, even a i5-12600K would still be about as good as it gets.
When you say watt(vs. what) perhaps you mean psu.
Here is a handy chart for that:

I would buy some 20% stronger to allow for a gpu upgrade.
Note that the K suffix processors come with integrated graphics to get you started.
Finding a good graphics card at < 2x msrp is tough these days.
