Often overlooked, power supplies are essential components of any PC and have a limited lifespan. Ignoring them can lead to damage or injury. Most power supplies have warranties between 5-10 years, but their lifespan can extend beyond 10 years. Attempted repairs should be avoided due to the risk of high-voltage shocks from charged capacitors. It’s recommended to upgrade your power supply regularly, especially after several builds or a decade of use. Dispose of old power supplies responsibly at e-waste recycling centers to avoid the risk of harm. Regular upgrades and proper disposal ensure the safety and longevity of your PC components.
