Product information

Description

The Rebeltec ATX 2.31 400W power supply is a reliable desktop PSU engineered to deliver a consistent 400W output for standard computer systems. Designed to meet the ATX v2.31 form factor, this unit ensures compatibility with a wide range of typical PC cases, providing stable electrical power to the motherboard, storage drives, and various peripherals. It serves as a dependable foundation for desktop builds that prioritize functional performance and steady energy delivery.

Advantages

This power supply unit offers a balanced approach to energy management for standard computing environments. Its adherence to the ATX v2.31 standard ensures that it integrates seamlessly into most mid-tower and desktop chassis designs. By providing a stable 400W output, it maintains the necessary voltage levels for essential components, reducing the risk of system instability during standard operation. The unit is built to support the power requirements of office workstations, home media centers, and basic computing setups, ensuring that your hardware receives consistent power without unnecessary complexity.

Suitable for

  • Office workstations and business desktop computers
  • Home multimedia and internet browsing PCs
  • Basic gaming builds with low-to-moderate power consumption
  • Replacement power units for standard ATX computer cases

This power supply may not be suitable for high-end gaming rigs, workstations equipped with multiple high-performance graphics cards, or systems requiring advanced overclocking capabilities. It is designed for standard loads and may lack the necessary wattage or specific high-end connectors required for enthusiast-grade hardware.

Key specifications

  • Output power: 400W
  • Form factor: ATX v2.31
  • Compatibility: Standard ATX desktop systems
  • Application: Office, home, and basic computing

To install the Rebeltec 400W power supply, first ensure your computer is disconnected from the main power source. Open your PC case and remove the existing power unit if necessary. Align the Rebeltec PSU with the mounting holes in the rear of the case and secure it using the appropriate screws. Connect the main 24-pin motherboard cable, the CPU power cable, and any required SATA or peripheral cables to your drives and components. Double-check all connections before closing the case and reconnecting the power cable to the wall outlet.

What to consider before purchase

  • Verify that your PC case supports the ATX form factor
  • Ensure the 400W output is sufficient for your total system component power draw
  • Check the connector requirements of your motherboard and graphics card
For optimal longevity and performance, ensure that the power supply intake fan is not obstructed by dust or cables, and maintain adequate airflow within the computer case to prevent overheating.
