Product information

Description

The MWE Bronze V2 power supply provides a straightforward and reliable way to supply stable power to a desktop system. With an 80 PLUS Bronze efficiency rating, DC-to-DC + LLC circuit design, a single +12V rail, active PFC and a temperature-sensitive 120 mm HDB fan, this PSU focuses on core performance and quiet operation. Flat black cables improve cable management and airflow, making the unit suitable for standard mid‑tier builds that require dependable, no-frills power delivery.

Advantages

The MWE Bronze V2 combines typical 85% efficiency with a thermally controlled 120 mm HDB fan to balance cooling and noise. Its DC-to-DC + LLC design and single +12V rail deliver stable voltages with reduced ripple, while flat black cables simplify routing and improve case airflow. Active PFC supports reliable operation across different mains conditions.

Key specifications

  • Efficiency certification: 80 PLUS Bronze (typical ~85%)
  • Cooling: 120 mm HDB fan, temperature-sensitive speed control
  • Circuit design: DC-to-DC + LLC (Dual Forward topology)
  • Rail configuration: Single +12V rail
  • Power factor correction: Active PFC
  • Cabling: Flat black flexible cables

How to use

Install the MWE Bronze V2 in your PC case using the standard PSU mounting holes and connect the main 24‑pin ATX, CPU 4/8‑pin, and necessary PCIe and SATA connectors to your components. Ensure adequate case ventilation so the thermally controlled 120 mm fan can operate effectively. Verify all cable connections before powering on the system and follow the motherboard and component manuals for proper connector orientation.

Recommendations

Use this PSU in typical desktop and mid‑tier gaming or productivity builds. Match the unit's wattage rating to your system's peak power draw, allow some headroom for future upgrades, and avoid running the supply continuously at its maximum rated load to extend lifespan.
