Common causes of power supply failure

by Lins » Wed Dec 10, 2025 4:08 pm

What are the most frequent reasons power supplies fail in workstations and servers, and what preventive steps can users take to extend lifespan and avoid sudden downtime?

One common cause of power supply failure is overheating - often due to dust buildup or inadequate airflow - which can degrade components over time. Another frequent reason is electrical stress: running a PSU near its maximum wattage for prolonged periods, or sudden voltage spikes, can shorten its lifespan. For example, I built a custom desktop for graphics design and noticed unstable voltages under load. So I bought a to replace the old unit. Preventive steps: keep the PSU clean and well-ventilated, don’t push it constantly at full load, use surge protection, and test-voltage stability periodically to avoid unexpected failures.
