To my knowledge, PSUs are rated up to a declared power output but unless you have hardware that requires all of its power, the PSU doesn’t put out the full charge.
Sure, but that difference is less than the variability based on load. The difference in efficiency between a Gold and Platinum PSU is like 4%, but load can vary that efficiency by 10 or 15%
What about a worse power bill?

The PSU doesn’t use more power just because it has a higher maximum capacity. Plus, a PSU is most efficient at partial loads (usually around 60-70%)
TIL
A PSU with an efficiency rating, like 80 Plus, will be more efficient than that PSU, even near 100% load (which it wouldn’t be usually).
