Seriously that's too much power for a rig.

Yes and no,psu's are most efficient at 50% load, so it would be above the 90% efficiency at 750 watts, on top off that full draw will wear them out faster, and they do loose capacity as they age. So someone with a 14900 or ryzen 9, and a 4090, that only uses it for games This would be the sweet spot. I'm not in this market , but I wish I was lol.
The other thing is this guy has a 10 year warranty. So it should be good for multiple builds. Especially in the high end bracket.

Then my Rmx850 w 5600x 6900xt probly pulls 650 max in AAA games. So it's rough on the unit.
By design shouldn't quality parts within the power supply negate any wear and tear? Buying $250 psu bc of concerns for wear and tear sounds like it's full of poor quality caps, coils, etc buyer has to worry about it. Makes me think all that marketing about Japanese capactators bla bla bla sounds like junk marketing.

The Japanese Capacitor is marketing BS, sort of,. Japanese Caps are better than other countries, but they are not Japanese SOLID STATE capacitors, like you see advertised on the motherboards. Electrolytic Caps Still wear with higher temp use, and have a much shorter lifespan(though unlike the Chinese Caps, they don't go boom too often). PSU's still use a mix of both types. They take advantage of the motherboard marketing them and people assume they are the same thing.
There are electrolytic caps in both yours and this one that are rated at 2000 hours. But they are at rated at 105C, so they should last much longer(psu's run at 40c or less usually). Running at peek will put it at about 55-60c. There is a general rule(not scientific, but accepted) that 10 degrees either way halves or doubles the life of Caps. So running a 1500 watt at half, will last (ideally) 2x longer than a similarly spec'd 850 running at 750, Just because it will be running cooler.
Now yours should still hit the lifespan of 10 years, and by that time you will want/need to upgrade for new features anyway. I am in the same boat with wattage used /peak as you. But I only game 10 hours a week, so the rest of the time I am well below the 50% peak efficiency, and the temps are much lower.
Now the loss of peak power is directly related to the liquid in the caps "evaporating/leaking", so basically just age.(I had a 650w that worked for 10 years, but eventually stopped working if my draw hit 450ish watts.
This is just a hobby, so if someone with real(non internet gathered) knowledge wants to correct me/ put me in my place I do welcome that.

Ideally, you want the smallest PSU you can get away with for greatest efficiency unless you're just playing maxed out cyber punk 24/7 any time the computer is on.
The only thing an oversized PSU offers is piece of mind that you won't need to get a larger one in the future.
80% at load is perfect for efficiency and is the goal.
In your example, you gain about 1% efficiency at 750w and lose about 1-10% efficiency at 0-700w.
Low power draw is the bane of all things efficiency. Titanium psu's alleviate that a bit.
80-90% under full load is about what you should shoot for, it's fine to get a slightly oversized psu for piece of mind and future upgrades but it's generally not a good idea for efficiency reasons, even for most gamers.
