The Cooler Master MasterWatt 750 is a power supply charger designed for mobile devices, with a total power output of 750 watts. It features active cooling with a 120mm fan and utilizes Active Power Factor Correction (PFC) technology. The charger is equipped with 16 AWG power cables to reduce resistance and increase efficiency.
The MasterWatt is 80 Plus Bronze certified, ensuring an average efficiency of 85%. It incorporates a durable LDB bearing 120mm Silencio FP fan that combines sealed bearings and quiet blades for long-lasting, quiet cooling. The semi-fanless mode allows the fan to remain idle under 15% load, providing noise-free basic computing.
The charger employs a dual forward and DC-to-DC circuit design for reliability and stability, especially in the +3.3V and +5V outputs. It also features more conductive 16 AWG PCI-e cables for improved efficiency and a safer user environment.
With a comprehensive power output distribution, the Cooler Master MasterWatt 750 is designed to efficiently and effectively power mobile devices while maintaining reliability and stability in various conditions.
