ATX PC Power Supply Circuit Diagram

The ATX power supply is the most common type of power supply used in desktop computers. It is a switched-mode power supply (SMPS) that converts AC input voltage to DC output voltages that can be used to power the components of a computer. The ATX power supply circuit diagram is shown below.

The ATX power supply is typically rated for 300 watts or more, and can provide up to 12 volts, 5 volts, and 3.3 volts of DC output. The 12 volt rail is the most powerful, and is used to power the CPU, graphics card, and other high-power components. The 5 volt rail is used to power the motherboard, memory, and other low-power components. The 3.3 volt rail is used to power some of the newer components on the motherboard. The ATX power supply is connected to the motherboard by a 24-pin connector. The 24-pin connector provides the power supply with the necessary signals to control the output voltages. The ATX power supply also has a 4-pin connector that provides power to the CPU. The ATX power supply is an essential component of any desktop computer. It provides the power that the computer needs to operate. By understanding the ATX power supply circuit diagram, you can better understand how your computer works. ## How Does an ATX Power Supply Work? The ATX power supply works by converting AC input voltage to DC output voltages. The AC input voltage is typically supplied by a wall outlet. The power supply uses a transformer to step down the AC input voltage to a lower voltage. The transformer is also used to create the different DC output voltages. The power supply uses a rectifier to convert the AC output voltage from the transformer to DC voltage. The rectifier is a diode bridge that allows current to flow in only one direction. The DC output voltage from the rectifier is then filtered to remove any unwanted noise. The power supply uses a voltage regulator to create the different DC output voltages. The voltage regulator is a circuit that uses feedback to maintain a constant output voltage. The different DC output voltages are used to power the components of a computer. ## ATX Power Supply Safety The ATX power supply is an important part of any computer. It is responsible for providing the power that the computer needs to operate. However, the ATX power supply can also be a source of danger if it is not properly used. There are a few things you can do to ensure the safety of your ATX power supply: *

Use a surge protector.

A surge protector can help to protect your ATX power supply from power surges. *

Don't overload the power supply.

Never connect more devices to the power supply than it is rated for. *

Don't open the power supply.

The ATX power supply is a sealed unit. Do not open it unless you are qualified to do so. By following these tips, you can help to ensure the safety of your ATX power supply. ## ATX Power Supply Specifications The ATX power supply is typically rated for 300 watts or more.
