ATX 850W 80Plus Gold Fully Modular Power Supply

Product Description

Features of ATX Power Supply:

1. Physical size: The physical size of ATX power supply is usually 150mm x 86mm x 140mm (standard ATX size), which is suitable for most of the standard ATX chassis.Computer Case

2. Power output: ATX power supplies offer different voltage and power outputs, including +3.3V, +5V, +12V, and -12V. Often spec'd power supplies also offer a +5V Standby voltage for powering standby requirements.Keyboard  Mouse

3. Connectors: ATX power supplies are equipped with a variety of connectors to connect various computer components. These include 20/24-pin ATX motherboard connectors, SATA power connectors for storage drives, Molex connectors for legacy devices, and PCIe power connectors for graphics cards.Motherboard Graphics Card

4. Energy efficiency and certification: Modern ATX power supplies often have energy efficiency certification standards, such as 80 PLUS certification, which indicates that they meet certain standards of energy efficiency. Energy-efficient power supplies convert power more efficiently, reducing energy waste and electricity bills.

5. Safety Protection: ATX power supplies are equipped with a variety of safety protection features, including over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection, etc., to ensure the safe operation of the power supply and computer system.

How ATX power supplies work:

The ATX power supply takes an AC power input (AC Input) and converts it to a DC voltage output (DC Output) using the built-in power supply unit. The following is the working process of ATX power supply:

1. Input Filtering: The power supply passes the AC Input through the Input Filtering Circuit for filtering, removing interference and noise to provide a clean power input.

2. Rectification and Filtering: AC power is converted to DC power and processed using rectifier and filter circuits to smooth the output voltage and reduce ripple and noise.

3. Transformer and Voltage Regulator: The converted DC power output is converted to the required different voltage outputs such as +3.3V, +5V, and +12V by means of a transformer and voltage regulator.

4. Power Management: The ATX power supply also includes power management functions that enable the power supply's standby mode (e.g. Soft-Off), as well as adjusting the power supply's voltage and power output according to demand, by communicating with the power management circuitry on the motherboard.

5. Temperature control and thermal management: ATX power supplies are usually equipped with temperature sensors and fans to monitor the power supply temperature and adjust the fan speed to ensure that the power supply operates within a safe temperature range.
