The Cooler Master MWE Gold V2 is a 550W power supply unit designed for standard ATX system builds. It holds an 80 PLUS Gold certification, which indicates up to 90% power efficiency under typical operating loads, contributing to lower energy consumption and reduced heat output. The unit utilizes Active Power Factor Correction (PFC) and is built to the ATX version 2.41 standard, providing stable and reliable power delivery for contemporary PC components. This model is engineered to operate in ambient temperatures up to 50°C.
For thermal management, the power supply is equipped with a 120mm fan that adjusts its speed based on system demand. The non-modular cabling system consists of flat black cables, which can facilitate straightforward routing and contribute to organized internal case layouts. A comprehensive suite of built-in protections, including over voltage, over power, short circuit, and overheating safeguards, is integrated to protect connected components. The internal design supports a Mean Time Between Failures (MTBF) of 100,000 hours.
