SMPS: Switch Mode Power Supply is one of the essential components of computer which ensures the proper working of your computer. SMPS is a electronic device installed in the CPU of computer which is responsible for conversion of A.C power supply into D.C power supply. SMPS energizes to motherboard, Hard disk drive, CD/DVD ROM etc. Now a day s most of the computer uses ATX SMPS with SATA cable attachment. In this article I will let you know about some common problems related to SMPS and how you can resolve them.
Combusted coil: A winding coil is present on the board which sometime gets burnt due to excessive flow of current. This problem can be identified easily by the smell or you can identify through the burnt marks located on the external section of the winding coil. It may be possible that internal loop is damaged and you can identify by using the blue ring tester or you have to depend on your nose.
Micro Crack: Improper maintenance and handling while transferring it form one place to another could also lead to physical damage which produces micro cracks on the IC or smaller sized components. It can t be identified easily and you need some professional magnifying glass to identify and repair it.
Faulty SMPS component:It may be possible that electrolytic capacitor or free wheeling diode damaged and causing problem in the proper functioning of SMPS. In many of the cases Power IC is the main culprit which is prone to error and you can use UC3842 IC Tester to detect the problems.
Main Circuit board Faults: If the power supply LED is not working properly for enhancing the speed and performance of computer.
