SEASONIC zdroj 550W FOCUS PX-550

Particulars

The long-awaited new line of Seasonic's FOCUS SGX is versatile in its application, and powerful with a small footprint. The FOCUS SGX is shipped with an SFX to ATX adapter bracket in the box, which allows the power supply to be mounted not only in the SFX form factor chassis, but also a standard ATX chassis should the user prefers to reserve more space for airflow inside the PC case. The Seasonic hybrid fan control is always enabled to optimize the cooling according to necessity.

80 PLUS^® Gold

The FOCUS PLUS Gold Series achieves 80 PLUS^® Gold certification with its 90 % efficiency at 50 % system load.

Compact SFX-L Size

The versatile FOCUS SGX measures at only 125 mm in both length and width. This super-compact size allows it to fit into various sized computer cases.

Smart and Silent Fan Control [S3FC]

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

• 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.

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.
