• A power surge or over voltage that trips a circuit breaker.
• Age: most of the warranties provided generally last for five to ten years. But still there’s no guarantee as the life depends on the usage of system.
• Electric interference: lightning, power spikes, etc. Voltage fluctuation.
• Dirt/foreign substance: cigarette smoke, house dust etc.
• Overheating and/or ventilation failures: the most common reasons of an SMPS failure is overheating. Make sure that the ventilation is free from dust and clutter. Also, do not keep the CPU in an enclosed desk.
