I’m sure in about 10-15 years 1000W PSUs will not be overkill…

I really hope you remembered to give yourself a bit of leeway on your PSU. I forgot that the last time I upgraded my pc. ended up with a lot of power failures running a pc that needed 850 watts on a 750 watt PSU. I’ve since stopped being so stupid and gave myself extra leeway with a 1k watt PSU. (my pc needed around 850 watts and I hate not having a bit of leeway for upgrading).
