Need help choosing right PSU

[22ZollAufm7er]

Hey, since i´m building my first Desktop PC and don´t have any experience i´d like to ask if anyone could help me.

PC - Specs:

Intel Core i9-10900KF 10x3.7GHz 125Watt

 Gainward RTX3070 220Watt (according to page)

 GIGABYTE B560 HD3, motherboard

 DeepCool GAMMAXX L360 A-RGB water cooling

 G.Skill DIMM 16GB DDR4-3200 Kit (2x 8GB stop), if possible calculate with 4x 8GB right away

 Hard drives: 1x SAMSUNG 970 EVO Plus 500GB, 1x SAMSUNG 870 QVO 1 TB

 Sharkoon REV220 tower case (2x 120mm fan with RGB, 3x120mm fan (is replaced by water cooling)

 

The Question at Hand would be, which PSU fits this Build with a little Wiggleroom so that nothing bad can happen. I don´t plan on Overclocking anything, and the build is the way it is because of my low Budget

 

Thanks for the help in Advance, best regards

Is this a build that is yet to happen or does it already exist? Because there iz a lot that can be improved here if still buying
