The Cooler Master MWE Bronze V3 is a 550W power supply unit designed for standard desktop computer builds. It operates with an 80 PLUS Bronze certification, which specifies an efficiency of up to 88% under typical load conditions. This model complies with the ATX 3.1 standard, providing compatibility with contemporary hardware configurations. It is engineered to deliver stable power for mid-range systems and includes active Power Factor Correction (PFC) to regulate voltage.
Constructed in a standard ATX form factor with a depth of 140 mm, the unit is sized for compatibility with most ATX chassis. A single 120 mm fan provides active cooling to maintain optimal operating temperatures. This model utilizes a non-modular cabling system, meaning all cables are permanently attached to the power supply. A comprehensive set of power protection features is integrated, including over power, over voltage, under voltage, and short circuit protection, to safeguard connected components.
