Compact and Silent Energy for Mini ITX Systems

The Be Quiet! SFX L Power 600W delivers 600 watts of continuous power in a compact SFX-L form factor, specifically designed for mini ITX PCs and compact gaming systems. This fully modular power supply combines German engineering with 80+ Gold efficiency, achieving up to 92% power conversion efficiency while maintaining exceptionally quiet operation.

Silent Operation with 120mm Temperature-Controlled Fan

Featuring a high-quality 120mm fan with temperature-controlled operation, this PSU produces only 8.5 dB(A) at 20% load and 14.5 dB(A) at 50% load. The sleeve bearing fan technology, combined with efficient heat management, ensures your system stays cool without excessive noise. Even at full 100% load, noise levels remain at a reasonable 28.7 dB(A).

Fully Modular Cable Management

The fully modular design provides maximum build flexibility with black flat cables extending up to 80cm. Connect only the cables you need: 1x ATX Mainboard (20+4 pin), 1x P4+4 CPU connector, 4x PCI-E 6+2 pin for multi-GPU configurations, 3x PATA 4-pin, and 6x SATA 15-pin connectors. This cable management system improves airflow and simplifies installation in tight spaces.

80+ Gold Efficiency and Reliable Power Delivery

The 80+ Gold certification guarantees up to 92% power conversion efficiency, reducing electricity costs and heat generation. The powerful single +12V rail design delivers stable power to both CPU and GPU, while LLC, Synchronous Rectifier, and DC-to-DC conversion circuits ensure consistent performance. High-quality Japanese capacitors provide a 100,000-hour MTBF rating for long-term reliability.

SFX-to-ATX Compatibility

The included SFX-to-ATX adapter bracket enables installation in larger ATX cases, making this PSU versatile for various build configurations. Whether you're building a compact Mini ITX system or need a small form factor PSU for a standard case, the SFX L Power 600W adapts to your needs.

Comprehensive Protection Features

Safety is built-in with a complete suite of protections: over current, over voltage, under voltage, short circuit, over temperature, and over power protection. The unit meets Energy Star 6.0 and ErP guidelines, features Zero Load design, and supports Intel's Deep Power Down C6/C7 mode with standby drain below 0.15 watts.

German Engineering and Quality

Designed and quality-controlled in Germany, the Be Quiet! SFX L Power 600W measures 64 x 125 x 130mm and weighs 1.16kg. Compatible with SFX 12V Version 3.3 and ATX 2.4 standards, it operates on AC 100-240V input with Active PFC. Backed by a 3-year warranty and international support.
