Fully modular ATX power supply with 850 W output and 80 Plus Gold certification. Rated power: 850 W. Cooling type: Active (with fan). Cable management: fully modular. 80 PLUS certification: 80 PLUS Gold. Form factor: ATX. The "Dust Free Rotation" technology reduces dust accumulation on the fan blades. The REVOLUTION D.F. 2 is a compact, fully modular 80 PLUS Gold certified power supply series featuring patented DFR technology that prevents dust buildup, ensuring a clean and long-lasting power supply. 100% Japanese electrolytic capacitors promise high manufacturing quality and a durable product. Based on an advanced Half Bridge LLC resonant converter and DC-to-DC circuitry, the power supply is capable of delivering perfect voltage regulation and very stable output performance. The intelligent fan control keeps the power supply fan in passive mode up to 20% load. Only after that does the 12 cm FDB silent fan provide continuous quiet active cooling. The 80 PLUS Gold certification of this power supply guarantees that at 100% load, an efficiency of at least 88% is achieved. This means that only a small portion of the input energy is converted to heat, resulting in less heat generation, lower energy consumption, and thus reduced ventilation needs.
