I mean, it should be fine, just because the PSU can provide more watts doesn’t mean the system is actually using that much power. I have an 800w PSU in my gaming rig, but its average load is only 240 - 320w during gaming (I’ve measured it by powering the system with a portable Ecoflow battery).

It runs fine, it’s just less efficient.

Where are you getting this from? Intuition?
I think the quiescent current and losses are less in a well engineered psu. If you get a 1kW light bulb and run 10W through it it will consume 10W.

This is verifiable in manufactures data sheets.
Efficiency at less than 20% and greater than 80% loads isn’t great relative to in between those ends.
This is compounded by lower wattage PSUs being more limited with regard to features and benefits.
If you end up with a 650w PSU and your system idles at 80 watts for the bulk of a working day you spend long periods of time in this less efficient window.
We need to see some quality 300w to 600w designs come back onto the market.
