A power supply unit (PSU) provides the computer power it needs to function. In a desktop computer, the ATX power supply is the most common type of PSU. This article looks at the different parts that make up an ATX power supply and how its features improve the structure of modern PCs.
Here is the content list:
Structural composition of ATX power supply
Advantages of ATX power supply
ATX power supply consists of five main components: transformer, rectifier bridge, filter capacitor, voltage regulator, and output connector.
The transformer receives AC power input and converts it into low-voltage DC current. It is connected to a rectifier bridge, which then converts the current into a full wave DC output. The signal passes through a filter capacitor that removes any waves or "ripples" to produce a stable current. After that, the signal is transmitted to a voltage regulator, where it is further filtered and adjusted so that only the correct voltage is sent from the PSU to all other components on the PC motherboard. The final part of the ATX power supply is its output connector, which distributes power within the device from each available rail, typically+3.3V,+5V,+12V, - 12V, and 5Vsb (+5V standby).
The ATX power supply is designed for maximum efficiency and provides some advantages over traditional designs in early PCs, such as using fewer internal components (reducing system heat), having more scalability options due to its smaller size, and better compatibility with new processors, as they can switch between low and high voltage settings based on hardware requirements, due to the fan design, which allows air to leave system components more effectively than previous traditional designs, noise is reduced, and backup functions are added, enabling the equipment to maintain power supply when not in use, but still maintain energy conservation in accordance with the 5Vsb track when the system is turned off or disconnected from the power grid, thereby using zero watts when not in operation.
Finally, security is improved through the use of securely locked connectors, so that only fully compatible cables or devices can be connected, without the risk of damage or loss of data/power due to incorrect connections, and without preventing unauthorized access/interference with the internal work of any given system due to physical barriers, as these power supplies typically require lockers to access content behind two-way lockable doors, multiple keys need to be operated simultaneously to open the enclosed area inside.
In terms of overall performance, today's ATX power supply provides greater stability compared to older models, allowing users to dynamically change power output based on workload, while providing efficient energy saving features, mainly due to its almost complete 80 Plus certification, which means that in some cases, the units provided will be rated as 80% minimum efficiency conditions, combining these factors, Making it an ideal choice - for those who want to upgrade their machines without replacing internal components - requires "juice extraction" before entering the installation phase - which makes life easier - all involved processes, including the user side - can generally help save time and money - as we all know, high-quality products never come cheap.
