Fanless design for completely silent operation, digital monitoring via MasterCTRL software, ATX 3.1 & PCIe 5.0 ready including 12V-2x6 cable, fully modular cable management for optimal organization The X Silent Edge Platinum 850 is a high-end power supply from Cooler Master that uncompromisingly focuses on silent performance. Thanks to its completely passive cooling, it is ideal for particularly noise-sensitive setups—from silent PCs to workstations. Completely fanless design prevents dust buildup and ensures absolute silence. Patented cooling concept with heat pipe technology and aluminum mold for efficient heat dissipation. Digital control unit with real-time monitoring via MasterCTRL software—including temperature and efficiency display. Supports ATX 3.1 standard and provides a PCIe 5.0-compliant 12V 2x6 cable—ideal for modern GPUs. Fully modular cable design ensures optimal airflow conditions and a tidy setup. Silent performance for enthusiasts With its innovative cooling architecture, the X Silent Edge completely forgoes active ventilation—even under heavy load, it remains passively cooled. This makes it perfect for users who value maximum efficiency and absolute silence. Innovative cooling technology The in-house aluminum heat mold combined with the copper heat pipe distributes generated heat evenly. This extends the lifespan of the components and keeps temperatures stably low even at 850 W output. Digital control & modern standards Through integrated microcontrollers, the power supply can be monitored via MasterCTRL software. It meets ATX 3.1 and provides all necessary cables for current GPU generations—including a dual 12V 2x6 interface for PCIe 5.1.
