Ideas on the Required Power of My PSU
750 to 850 quality PSU. The market seems a bit overvalued, so better-quality 1000W options might still be available at a lower price.

Well that gives you a range of 600 to 699, but it doesn't include fans or pumps, etc. It's not a terrible guess, but usually you should aim to keep the PSU at about 50 to 80% load, so a 750W unit should easily cover that need. PSUs also lose efficiency over time and might not perform as rated after many years.
Other tools tend to ignore fans, pumps, and also tend to overestimate power needs for things like memory and motherboards.
Keep in mind this is 100% CPU and GPU usage. You're unlikely to hit that outside of benchmarking.
GPUs can handle their full rating easily, though sometimes they do.
Your main priority is to purchase a reliable PSU. A warranty of seven years or more is typically a sign of good quality.
Graphics cards often experience significant power spikes that exceed their standard draw.
A 750-850w could suffice, but a 950w unit would provide better performance and quieter operation, operating smoothly within the middle of its capacity.
