The ASRock Steel Legend SL-850G is an 850-watt power supply unit engineered for stable and efficient power delivery in demanding PC builds. It is certified 80 PLUS Gold and Cybenetics Platinum, indicating high energy efficiency across different load levels. The unit adheres to ATX 3.1 and PCIe 5.1 standards, providing compatibility with current-generation hardware. For modern graphics cards, it includes a native 12V-2x6 pin connector, which features a dual-color design to confirm a secure connection.
This PSU employs a fully modular cabling system, which allows users to connect only the necessary cables, simplifying installation and improving internal airflow. Thermal performance is managed by a 135mm fan with an intelligent controller that can operate in a semi-passive mode for silent operation at low loads. The internal design incorporates Japanese capacitors for consistent voltage regulation and long-term reliability. A comprehensive set of protection circuits, including OCP, OVP, SCP, OTP, and OPP, is built-in to safeguard system components from electrical faults.
