Switching Power Supply For PC

With all the certifications UL, ETL, FCC, CE, CB, GS, CCC, CQC, PSE, KC, KCC, SAA, RCM, etc.

For computers, the two most important hardware are CPU and power supply. CPU is equivalent to human brain and power supply is equivalent to human heart. According to statistics, 40% - 60% of computer failures are caused by power supply, while a power supply only accounts for 2% - 3% of the whole machine. Improper selection of power supply may not only burn CPU, motherboard and hard disk, but also cause other losses.

when the power supply enters the power supply, the high-frequency clutter and interference signals are removed through the yoke coil and capacitor filter, and then the high-voltage DC power is obtained through rectification and filtering, and then it enters the core part of the power supply switch circuit. The switching circuit converts DC into high-frequency pulsating DC, and then sends high-frequency switching transformer to step down, and then filters out the high-frequency AC part, so as to finally output relatively pure low-voltage DC for computer use.
