The Cooler Master MWE Bronze V2 is an ATX power supply unit designed to deliver 550 watts of continuous power. It holds an 80 PLUS Bronze certification, signifying a typical operational efficiency of 85% under load. The internal design utilizes a DC-to-DC converter with LLC circuit topology to provide stable voltage regulation for modern components. This unit adheres to the ATX version 2.52 standard, ensuring compatibility with current motherboard power requirements and system sleep states.
This model features a non-modular design where all cables are permanently attached. Cooling is managed by a single 120mm fan that provides active airflow, and the unit is rated for operation in ambient temperatures up to 40°C. A comprehensive suite of built-in protections, including over-voltage, over-power, and short-circuit protection, helps to safeguard connected hardware. The standard ATX dimensions of 150mm x 86mm x 140mm allow for installation in most PC cases.
