Focus Plus 550 Platinum
The fully modular, 80 PLUS® Platinum rated FOCUS+ Platinum 550 watt unit is based on the DC to DC Converter Design and its electric performance characteristics are impressive with their tight voltage regulation. These power supplies use high temperature Japanese capacitors to ensure stability under extreme conditions. Besides its stability and remarkable output characteristics, this unit has the highest power density in its class. Silence enthusiasts will appreciate the Seasonic Hybrid Silent Fan Control system that is the industry’s first three-phased advanced thermal control to achieve optimal balance between silence and cooling.
Fluid Dynamic Fan Bearing

High Performance Fan Bearings
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.
Hybrid Silent Fan Control

Endless Colour Combinations
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.
