Hybrid Silent fan Control

The industry’s first, Seasonic patented, advanced three-phased thermal control achieves optimal between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode.

Benefits of this design

Reduced noise without increase in temperature;
Extended fan life due to the reduced number of fan rotations;
Optimized heat dissipation at all times;
Unsurpassed silent performance in Fanless Mode.

Additionally, there is a switch at the back of the power supply which allows users to customize their cooling needs by selecting between the Seasonic S2FC (fan control without Fanless Mode) and the S³FC (fan control including Fanless Mode).

Sanyo Denki Fan

The world-renowned Sanyo Denki ball bearing fans are made of the highest quality components to ensure ultra-low noise performance. The fan’s perfect balance and even rotations are achieved via the use of spoon-shaped, high-density plastic fan blades that are finished off with smoothed leading edges. Sanyo Denki fans are known for their strict tolerance ball bearings and precision copper axels. Instead of the industry standard of two balancing points they use three points to strengthen the mount and further stabilize the blade.

105 °C Japanese Capacitor

Premium quality Japanese capacitors with 105 °C rating increase overall reliability and extend product life.

DC to DC Converter Design

The step down DC to DC converter design allows the power supply to be able to serve system components with various voltage needs. Not only is it a flexible, clean voltage conversion solution but it also maximizes the 12 V DC rail output, delivers superior dynamic response and , ultimately, provides for greater system stability.

Tight Voltage Regulation (3 %)

Seasonic’s advanced design is to improve load regulation which reduces voltage variations to provide smooth and stable operations.

“The new X-Series KM3 650 W is another flawless power supply from Seasonic, targeted to users who demand only “the best.” Its efficiency surpassed the numbers promised by the 80 Plus Gold certification, noise and ripple levels were very low, and voltage regulation was outstanding, with the main positive voltages (+12 V, +5 V, and +3.3 V) within 1% of their nominal values. The ATX12V specification allows a 5% deviation, and we usually consider units with 3% voltage regulation as “flawless.””

“A nova X-Series KM3 650 W é mais uma fonte de alimentação impecável da Seasonic, direcionada a usuários que exigem o melhor. Sua eficiência ultrapassou os números prometidos pela certificação 80 Plus Gold, os níveis de oscilação e ruído foram bem baixos e a regulação de tensão foi excelente, com as principais tensões positivas (+12 V, +5 V e +3,3 V) ficando dentro de 1% de seus valores nominais. A especificação ATX12V permite uma tolerância de 5% e nós geralmente consideramos fontes com regulação de tensão de 3% como sendo impecáveis.”
