I have a PC that's been running smoothly without any issues, but I've got a question about my power supply unit (PSU). It's a Corsair 850W model and it's about 14 years old now. My setup includes a Ryzen 5900X, 64GB of RAM, and an RTX 4080 Super, along with three NVMe drives, one SSD, and a couple of USB SSDs. I use my PC fairly regularly, but there are times when it sits unused for months. Considering its age, do you think it's time to replace the PSU?

If you can afford it, definitely get a new one. I've seen too many PSUs go bad and take down other components with them, and replacing just the PSU is cheaper than replacing the entire system. It’s better to be safe than sorry!
Honestly, it would be smart to upgrade. Even though it still works, at 14 years old, a PSU can start having ripple issues that can harm other components. Plus, with the recent advancements in PSU efficiency and performance, you might even notice lower heat and noise levels. Consider checking for any good deals on new PSUs.
It's a lot of nice hardware you're risking with that old PSU. While it might still be working fine, the older it gets, the more likely it is to fail. Replacing it sooner rather than later could save you a lot of trouble and money in the long run.
I would definitely recommend replacing it. There’s a lot of debate about this topic, but generally speaking, using an out-of-warranty PSU with newer components isn’t wise. Capacitors can degrade over time, and with a high-end card like the 4080 Super, you wouldn’t want to risk it getting damaged by an old power supply.
While it seems to be running fine now, old power supplies can be ticking time bombs. If it dies suddenly, it could potentially damage more expensive components like your GPU. 14 years is a solid run; replacing it could help ensure everything continues to work smoothly.
