The S12II Bronze Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic S12II-Series achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the S12II Bronze series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the S12II units maintain important features such as the stable and proven Double Forward Converter circuit design, the industry’s leading Smart and Silent Fan Control (S2FC) and the use of high reliability Japanese brand capacitors.
The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill.
The 80 PLUS® Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. Sea Sonic’s Bronze Series is an economical choice with great performance and high built-in value.
S2FC - Smart and Silent Fan Control
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
Fluid Dynamic Fan Bearing
High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.
How it works
When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
