Do PSUs need replacing over time?

[Grim5]

I've seen a fair few cases where retrospectively I've found out people are running the latest hardware on an ancient PSU, and going through OS reinstalls and RMAing the CPU, motherboard, etc. and looking back been like hmmm.

Can confirm my own PC was unstable for 2 years due to a bad Corsair PSU

I have been running a corsair ax760i for the last maybe 9 years? Probably do need to change it out but shows no sign of issues

I changed mine because of the technology upgrades as I have a very power hungey system and need the extra protection it gives.
