Product information

Description

Cooler Master MWE Bronze 550 V3 230V is an ATX power supply designed for mainstream desktop systems and modern GPUs. It features ATX 3.1 compatibility, an embossed cable finish for improved handling, a hydrodynamic bearing cooling fan, DC-to-DC + LLC topology, and 80 Plus Bronze certified efficiency with a five-year warranty.

Advantages

The unit supports ATX 3.1 peak power demands, offering up to 1.5× short-term power above rated wattage for compatibility with current high-performance GPUs. The embossed cable improves cable grip and appearance, while the quiet HDB fan and high-temperature resilience (operational up to 40°C) enable sustained, reliable operation. A DC-to-DC + LLC circuit design helps stabilize voltages and improve efficiency across loads.

Key specifications

  • Model: MWE Bronze 550 V3 230V
  • Form factor: ATX
  • Efficiency: 80 Plus Bronze (≈88% at typical load)
  • Fan: Hydrodynamic bearing (quiet HDB)
  • Topology: DC-to-DC + LLC
  • ATX support: ATX 3.1 (supports 1.5× peak power above rated)
  • Operating temperature: up to 40°C
  • Cable: Embossed texture
  • Warranty: 5 years

How to use

Install the MWE Bronze 550 V3 into an ATX-compatible case following standard PSU mounting and grounding practices. Connect the 24-pin ATX, CPU power, PCIe, SATA and peripheral connectors to your motherboard, GPU and drives as required. Ensure adequate case airflow and keep ambient temperature within recommended limits to maintain efficiency and longevity. Use the PSU only with systems whose combined power draw does not exceed recommended continuous ratings; short-term ATX 3.1 peak capability can cover transient GPU spikes.

Recommendations

For system planning, use Cooler Master's PSU calculator or similar tools to verify required wattage including peak GPU demands, and confirm connector compatibility with your GPU model before installation.
