ATX power supply working principle and classification

I. Working Principle

The ATX Power Supply is mainly composed of several parts, including the rectifier bridge, DC filter capacitor, transformer, switching power supply, winding and heat sink, etc. These parts work together to ensure the stable and safe operation of the computer. The most important of these is the rectifier bridge, which converts AC power to DC power; and the filter capacitor, which filters out the noise generated by the power supply. The transformer is the core component of the ATX power supply, which can step down the high-voltage AC power to low-voltage DC power, and has a good voltage regulation performance. Finally, in order to ensure the efficiency and thermal performance of the power supply, ATX power supplies also need to be equipped with switching power supplies, efficient thermal fans and wire-wound thermal design.

II. Introduction to Classification

According to the power of the power supply, ATX power supplies are mainly divided into several grades such as 300W, 400W, 500W, 600W, 700W, etc. Readers can choose according to their needs and budget. In addition, according to the voltage output of the power supply and the number of cable interfaces and the standard specifications, ATX power supplies can also be divided into two series, AT and ATX. Among them, the AT series power supplies have a voltage output of -5V, but the ATX series power supplies have abandoned this technology because this interface is no longer needed in modern computers. In addition, in terms of the number of cable interfaces, ATX power supplies have a wide variety of interfaces, including motherboard power interfaces, IDE hard drive power interfaces, SATA hard drive power interfaces, PCI-E interfaces, and so on.TFX SFX Power Supply
