The Corsair SF-L Series SF850L 850W Fully Modular Low-Noise SFX Power Supply is a high-performance, compact power supply designed for small form factor (SFF) builds. It combines 850W of continuous power with 80 PLUS Gold efficiency and a fully modular design, ensuring excellent performance and cable management. The SF850L is part of Corsair’s SF-L Series, which focuses on delivering high-quality, low-noise operation while maintaining a compact form factor suitable for SFX-compatible cases.

With its low-noise cooling, high efficiency, and small footprint, the SF850L is an ideal choice for users looking to build powerful systems in compact cases like Mini-ITX or other small form factor (SFF) builds. It’s particularly well-suited for high-performance gaming PCs, workstations, and custom builds where space is limited but reliable, efficient power is still required.

Features

• 80 PLUS Gold Efficiency: The 80 PLUS Gold certification ensures that the SF850L operates with high efficiency, minimizing energy waste and heat output. This leads to reduced power consumption, quieter operation, and less stress on your system components.

• Compact SFX Design: With its SFX form factor, the SF850L is perfect for building small form factor (SFF) PCs. Whether you’re using a Mini-ITX case or a compact tower, this PSU fits easily into tight spaces, delivering high performance without sacrificing efficiency or stability.

• Fully Modular Design: The fully modular cables allow for optimal cable management, ensuring that you only use the cables you need. This results in a cleaner, more organized build with better airflow, which is essential in SFF builds where space is limited.

• Low Noise Operation: Thanks to the 92mm fan and low-noise design, the SF850L operates quietly, making it ideal for silent PC builds or environments where noise levels need to be minimized.

• High Power Output: With 850W of continuous power, the SF850L is capable of supporting high-performance gaming setups, workstations, and multi-GPU configurations. It provides more than enough power for demanding components, while maintaining low noise and high efficiency.

• Long-Term Reliability: With a 7-year warranty and 100,000-hour MTBF, the SF850L offers long-term reliability and peace of mind, backed by Corsair’s reputation for high-quality and durable power supplies.
