What is the lifespan of a PSU?
5-6 years5-6 years is about the realistic life expectancy for decent performance out of a typical PSU before the electrolytic capacitors see enough aging that it becomes harder for it to operate at its rated load and/or efficiency..
What happens if you have too much power supply?
There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout. The power supply will only provide the needed wattage.
