Native PCIe 12V-2×6 Cable Dual Color Design
With ASRock Classic Green connectors, users can easily see if the connector has been plugged properly.

iCOOL Intelligent Fan Control Mode
iCOOL Mode ON: The power supply runs more efficiently. The fan stays off during low to medium loads, reducing noise and improving energy efficiency. The fan only activates when the load or temperature increases.
iCOOL Mode OFF: The fan runs continuously, regardless of load. This may increase noise slightly but provides consistent cooling and better performance under heavy loads.

80 PLUS & CYBENETICS CERTIFIED
The Steel Legend series power supply unit offers options of 1200W, 1000W, 850W, 750W, and 650W, available in “Steel Black” and “Steel White” ideal for mainstream systems. Certified for 80 PLUS Gold efficiency and Cybenetics Platinum rating, along with LAMBDA A+/A acoustic certification, it ensures outstanding energy performance.

CYBENETICS LAMBDA A
The Steel Legend series power supply earning the prestigious Cybenetics Lambda A certification.
