    Tips: What’s a switching power supply (SMPS)?

    Switching power supply, or switch-mode power supply (SMPS) modulates pulses of input voltage by closing and opening the circuit of electronic switching devices (such as transistor, field-effect transistor, and silicon controlled thyratron) to fulfill output voltage adjustment, automatic voltage stabilization, and continuous voltage conversion between DC/AC or DC/DC. It is composed of PWM integrated control circuit, and MOSFET. With evolution of power electronics, switching power supply has experienced innovation in technical level. It is now widely applied to electronic devices by virtue of its outstanding performance in size, weight and efficiency. The switching power supply has become an indispensable power supply mode for booming electronic information industry.

    Existing reviews of 5V DC 10A 50W Switching Power Supply
    Good shopping, inexpensive
    I bought this inexpensive switching power supply to use for my computer, and sometimes for decorative lights. The voltage can be adjusted down to 5V to fit my computer. As thermal fans do not run under low load, this unit is quiet. However, you should install a power cord for it. Inline switch is also needed. After all the steps finished, you can enjoy your work.
