Then change it every 2–4 years.
If you just have a home PC that is used for occasional gaming, every 5–8 years should be sufficient..
Do PSU degrade over time?
A PSU will degrade over time. … The reason computer PSUs typically last (if they are decent quality) is the fact that they are often far overspecced for the actual wattage you put on them. A 800W PSU that gets 200W load for 4 hours a day will live longer than one that has 750W load 24/7.
Do PSU lose power over time?
When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years” ..

Why does a PSU fail?

Can I use my old PSU?
While old power supplies might still work, it could be because your old PC hardware didn’t need too much power. Upgrading the CPU, motherboard, and graphics card could change that. A supply that fails can, in the worst case, take out other components in your PC or even catch fire.
