Abstract—Recently, reliability is one of the serious
requirements of electronic systems. The numbers of system
failures, repair cost, guarantee and etc are estimated by
reliability prediction. In this paper, the reliability of a switching
power supply, which is used for personal computers, evaluates.
It will show that electrolytic capacitors, used in input and
output filters, play a significant role on the computer’s power
supply’s life time. Ambient temperature, derating, and
capacitance effect on the failure rate will discuss. The remedies
are recommended for more life time.
Index Terms—Electrolytic capacitor, reliability, SMPS, PC.
