S12G-550

Amongst Sea Sonic’s wide range of award winning products, the S12G-550 is well-furnished with high quality components that provide solid performance. Intelligent thermal control ensures an optimal balance between silence and cooling and honeycomb-shaped ventilation grid ensures that heat can escape the interior without much resistance. The 80 PLUS® Gold certification guarantees that at 230 volt input and around 50 % load the unit will operate at a minimum of 90 % efficiency (92% efficiency at 110 volt input). This remarkable performance will result in quieter operation, lower operating costs and less excess heat.

80 PLUS®Gold

Seasonic was the forerunner of creating the very first 80 PLUS® Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency. The highly efficient 80 PLUS® Gold certification guarantees greater than 87 %, 90 % and 87 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The clear advantage of buying a power supply with 80 PLUS® Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.

Ultra Ventilation

The most efficient design to minimize airflow resistance for maximum cooling.

Fluid Dyanamic 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.
The following illustration depicts the main characteristics of the FDB fans:
