ATX 850W Revolution D.F. ERF
Up to 92% efficiency at 230VAC between 20 and 100% load. The REVOLUTION D.F. series is 80PLUS® Gold certified.
REVOLUTION D.F. helps systems to meet the EU eco-design directive 2013 ErP Lot 6 and 2014 ErP Lot 3 (< 0.5W in standby mode*) due to a high-efficient 5V standby (+5Vsb) circuitry. Moreover it supports the EU regulation no. 617/2013 demanding amongst others 85% efficiency at 50% load and 82% at 20% and 100% load. * only in combination with an ErP ready mainboard
The DC-to-DC design generates the secondary voltages (+5V and +3.3V) from the primary voltage rail (+12V). The positive effect is higher efficiency, clean output voltages (low ripple noise) and a perfect voltage regulation at all loads.
At least four 6+2P (8P) PCI-E connectors ensure power for multi-GPU systems (MGPU & SLI™) and overclocked processors.
A multi-rail design with four 12V rails distributes the power with maximum stability and safety.
The fully modular Flat cable management allows an easy system installation and cable routing and improves the air circulation inside the case.
Extended 70cm CPU connector cable for installation in large cases.
The integrated 13.9cm Enermax fan with patented Twister Bearing™ technology ensures an efficient and continuously silent cooling and long lifetime with up to 160,000 hours MTBF.
The patented technology DFR™ (Dust Free Rotation) reduces the dust accumulation on the fan blades.
After starting the PSU, the fan spins in reverse at full speed for a few seconds removing dust.
Afterwards it returns to normal operation.
Smart Airflow Control
The SAC (Smart Airflow Control) design keeps the PSU fan spinning at almost inaudible 400 RPM upto 70% load to provide the optimal silent experience.
The D.F Switch is placed at the back of the PSU and allows manual activativation of the DFR™ funktion. The D.F. Switch turns the fan immediately into backspin, removing accumulated dust. Regular use of the DFR™ funktion can help to reduce dust accumulation and prolong the lifespan of the product.
