– 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 2×6 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 2×6 interface for PCIe 5.1.
