Why did you put an 850W power supply in that? You could probably put a 650W that's much nicer for the same price.
It was on sale and I thought "eh what the hell I'll upgrade sometime down the road"
Yeah, as long as you're pulling more than like 20% of the rated power then having a slightly overspec power supply is only going to bring you good things.
What about a worse power bill?
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.
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).
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%
