PSU dying?

[MyLittleFella]

Hello everyone, I accessed my firmware settings earlier today, and I realized this:
My PSU is a Corsair CX750M (yellow box, black label) from 2015/2016
Now, the thing is: When I run  cinebench R15.0, isntead of 945 points as usual it goes down sometimes up to 890 points.

What you guys think?

Do you have any coil whine under load? What are your CPU temps at load? You could be thermal throttling which would explain a lower score. Are you noticing any stability issues, BSOD's or random shut off's. That PSU has a 5 year warranty as long as you didn't get it off eBay or second hand. A lower score while bench marking wouldn't be enough for an RMA but if the PSU is causing stability issues Corsair should cover you.

PC is fine, no stablity issues. The only thing that gets my attention is the low score. Temps under load get up to 60~~75 tops (rare, but it happens)

No other changes to your computer, any new hardware?

If you're using an extension cord, PDU, or a UPS try plugging it directly into the wall outlet and test it.

Power supplies don't affect Cinebench scores, and software voltage readings are also not accurate.
