Product information

Description

The FSP FSP400-50AAC is a reliable 400 W power supply unit designed to deliver stable and efficient energy to standard desktop computer systems. Built with the ATX form factor, this unit fits a wide variety of standard PC cases and supports a worldwide AC input voltage range from 90 to 264 V. Featuring an 80 PLUS Bronze certification, it ensures optimized energy consumption and reduced heat generation during daily operation. The integrated active cooling system utilizes a quiet 12 cm fan to maintain optimal thermal performance while keeping noise levels to a minimum. Non-modular cabling provides straightforward cable management for standard builds.

Advantages

This power supply unit offers dependable performance backed by an 80 PLUS Bronze efficiency rating, helping to lower electricity usage and operating temperatures. The single 12V rail design efficiently handles the power demands of standard PC components, while active Power Factor Correction ensures stable electrical characteristics. Thanks to the 12 cm cooling fan, the unit operates quietly, making it well-suited for office environments and home setups where low noise is important. Comprehensive safety certifications provide additional peace of mind regarding electrical safety.

Suitable for

  • Building or upgrading standard office desktop computers
  • Replacing older or failing power supply units in home PCs
  • General-purpose desktop systems operating on standard AC voltage

This unit may not be suitable for high-end gaming computers, workstations with multiple high-power graphics cards, or overclocked systems that require higher wattage capacities exceeding 400 W.

Key specifications

  • Total power: 400 W
  • Form factor: ATX
  • 80 PLUS certification: 80 PLUS Bronze
  • AC input voltage: 90 - 264 V
  • Cabling type: Non-Modular
  • Cooling type: Active with 12 cm fan
  • Power factor correction: Active PFC

Installation involves mounting the power supply unit inside a compatible ATX computer case using standard screws and connecting the non-modular cables to the motherboard, storage drives, and other system components. Ensure the computer is disconnected from the main power source before installation. Route the cables carefully to avoid obstruction of airflow within the case.

What to consider before purchase

  • Verify that your computer system's total power consumption does not exceed the 400 W capacity
  • Check that your computer case supports the standard ATX power supply form factor
  • Confirm that non-modular cabling meets your system build preferences
Usage recommendations: Ensure adequate ventilation around your computer case to allow the active cooling fan to dissipate heat effectively. Regularly check and clean dust filters near the power supply intake to maintain optimal airflow and prolong the lifespan of the unit.
