A switched-mode power supply (switching-mode power supply, SMPS, or simply switcher) is an electronic power supply that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. Like other types of power supplies, an SMPS transfers power from a source like the electrical power grid to a load (e.g., a personal computer) while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.
Unlike a linear power supply, the pass transistor of a switching mode supply switches very quickly (typically between 50 kHz and 1 MHz) between full-on and full-off states, which minimizes wasted energy. Voltage regulation is provided by varying the ratio of on to off time. In contrast, a linear power supply must dissipate the excess voltage to regulate the output. This higher efficiency is the chief advantage of a switch-mode power supply.
Switching regulators are used as replacements for the linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated, their switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.

Switched Mode Power Supply
smps out voltage is 12volt.. A switch mode power supply can have an output voltage of any value. However, common values are 5, 12 and 24V.

smps means switch mode power supply

Connect Pin No. 14 & 15 on SMPS, if the fan moves then SMPS is working fine else SMPS is faulty.
SMPS are mainly 4: flyback pushpull halfbridge full bridge
by shorting the red and green pin of smps we can check it working or not
Ya easily. just take the ATX smps and pull out it's two extra pin from it's power plug and set it to the PC.
motherboard problem, other wise change smps then turn on computer if it is boot-up smps problem. that's problem occur in smps or motherbordAnswermotherboard problem, other wise change smps then turn on computer if it is boot-up smps problem. that's problem occur in smps or motherbord
SMPS stands for switched mode power supply
There are various ways to troubleshoot smps of PC. SMPS stands for switching mode power supply. You can start by trying if it works elsewhere and if this the case, then it means that your motherboard is faulty.
