Cooler Master X Silent Edge 80 PLUS Platinum Power Supply, ATX 3.1, PCIe 5.1 - 850 watts,
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 aluminium mould 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 aluminium heat mould 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.
