Question Is it worth a PSU upgrade for a 5 year old Corsair RM850x (2018)?

[_dawn_chorus_]

I'm upgrading my whole system but was hoping to reuse the PSU. Given that it has a 10yr warranty I assumed it will still last a good while, but opinions seem to vary wildly from different sources. I am seeing some people suggest PSU parts degrade faster than others. Is this really an issue? I have had the PSU 5 years and it has been feeding an 8700k with a 1080, then a 2080s, then a 3080FE usually gaming anywhere from 2-12 hours a week. So it hasn't exactly been ridden hard over the years. Maybe running ~400w under a heavier real world load. It has been plugged into a quality surge protector and is unplugged entirely during storms or immediately after power loss.

It should be more than enough for the upgrade: (13600k & 4080FE, 2x16 DDR5 6400mhz, 2x m.2 drives, 4x sata drives, 3x 140mm fans, 1x 120mm).
Calculators put it at around 640w load and since transient power spikes aren't really an issue with the 40 series that seems like plenty of headroom.
Also I won't be running furmark/cinebench/ etc, just gaming at 1440p 120hz or 4k 60hz and music production mostly, digital art as well and some light video editing, I am guessing I will rarely if ever surpass 500w total system draw.

Not too keen on upgrading because it seems the new RMx 2021 supplies are at the very least double the noise output, or are plagued with coil whine issues. I am very noise sensitive.

It should still be fine.

I would absolutely use a quality unit like that, appropriate for the load, and still in warranty.

No real reason to replace it yet.

I have my 1000 Watt HXI from 2016, runs great still in warranty. ZERO issues.

Keep rocking it
