Description

Asrock Steel Legend 850W Quiet Powerhouse with Platinum-Class Output

Ultra-Quiet Operation with Platinum Performance

Designed for modern performance rigs, this power supply combines premium certifications with forward-thinking features. With 80 PLUS® Gold, Cybenetics Platinum, and Lambda A+ acoustic ratings, it delivers highly efficient power with ultra-quiet operation. Native support for ATX 3.1 and PCIe 5.1, along with a 12V-2×6 connector, ensures it’s fully ready for the next generation of GPUs and components.

Intelligent Cooling Meets Durable Engineering

Cooling is intelligently handled by a 135mm Fluid Dynamic Bearing fan with iCOOL Intelligent Fan Control. This system allows users to toggle between energy-saving silent mode or constant airflow for demanding loads. At lower power demands, the fan stays off entirely, maintaining near-silent operation. The fan only ramps up when needed—balancing cooling, longevity, and acoustics.

Silence, Stability, and Style for High-End Systems

Internally, 100% Japanese capacitors rated at 105°C ensure durability and stability, even under stress. The fully modular design, dual-color cable connectors, and protective features like OVP, OPP, SCP, and OTP provide not only exceptional performance but also long-term safety and ease of build. Backed by a 10-year warranty, this PSU is built to last and perform in silence.
