Introduction of SMPS- Switch Mode Power Supply

1. COMPUTER HARDWARE TOPIC SMPS (SWITCH MODE POWER SUPPLY)

2. SMPS: means Switch Mode Power Supply, they are Digital in  Nature.They  step down voltage by “switching” it on and off, hence their name. SMPS converts  AC Voltage  to  DC voltage . All the computer parts work on DC supply.SMPS supplies DC voltage through connectors on Motherboard and various other devices. WHAT IS SMPS

3. SMPS IMAGE

4. As you can see back side of SMPS. FAN is used to dissipate/reduce the heat generated in SMPS. In Fig  , there are two AC power sockets. One is for AC 220 V input to SMPS and the other is for output AC 220 V to your Monitor/LCD. In some SMPS there is only one socket for AC 220 V input to SMPS . In this case the monitor will take input supply directly from other power source SMPS

5. AT POWER CONNECTOR ATX POWER CONNECTOR STANDARD PHERIPHERALS POWER CONNECTOR FLOPPY DRIVE POWER CONNECTOR TYPES OF POWER CONNECTOR IN SMPS

6. THIS TYPE OF POWER CONNECTOR HAVE 2 COONECTOR WHICH ONE IS P8 AND ANOTHER ONE IS P9 USE IN OLD PC. AT POWER CONNECTOR

7. USES A SINGLE P1 POWER CONNECTOR THE P1 HAS A NOTCHED CONNETOR TO ENSURE PROPER INSTALLATION ATX POWER CONNECTOR

8. PRIMARILY USED FOR DEVICES THAT REQUIRE 12V AND 5V OF POWER A MOLEX CONNECTOR USES “CHAMFERS” (NOTCHES) FOR EASY INSTALLATION INSTALLING A MOLEX BACKWARDS CAN DESTORY THE DEVICES INTO WHICH THE MOLEX INTO CONNECTED. STANDARD PHERIPHERALS POWER CONNECTOR

9. PRIMARILY FOR 3.5-INCH FLOPPY DRIVES CARE SHOULD BE TAKEN WHEN INSTALLING MINI CONNECTORS (BERG CONNECTORS). FLOPPY DRIVE POWER CONNECTOR

10. OCCASIONALLY, THERE ARE NOT ENOUGH CONNECTORS TO POWER ALL THE DEVICES INSIDE A PC SPLITTERS ARE USED TO CREATE MORE CONNECTIONS SPILLTERS AND ADAPTERS

11. MANY MOTHERBOARD REQUIRE A SECOND, FOUR-WIRE CONNECTOR TO PUSH MORE 12-VOLT POWER INTO THE BOARD P4 CONNECTOR
