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.


80 PLUS??Platinum
The higher the level of efficiency of the power supply, the less power gets wasted in the form of excess heat . The 80 PLUS?? Platinum certification guarantees greater than 90 %, 92 % and 89 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The Seasonic Platinum Series represents the highest level of technology and efficiency achievement of Sea Sonic during its 40 years of commitment to engineering excellence.
