PSUs are waaaaay more efficient when operating closer to their rated capacity. Pulling 200W through a 1kW power supply is like making a marathon runner breathe through a straw.
But it doesn’t make that much of a difference. The efficiency swing is maybe 10%. Like an bronze 80 rated PSU will have a minimum efficiency of 80%, but even if you’re at the 50% load mark it won’t be over 90% efficient.
The main point (to me anyways) is that its dumb to pay more for a power supply just so you can pay "more* on your power bill. If your idle load is 100W and your gaming load is 300W, you’ve got no reason running more than a 600W PSU
While true. How much would it actually save you in electricity? If you upgrade every year wouldn’t it be cheaper to just buy the bigger psu outright and pay the extra cost in electricity so you don’t have to buy another PSU when you get more power hungry components.

The sweet spot is the 40-60% load.
