Seasonic SSR-550PX FOCUS 550W 80 PLUS Platinum ATX12V Power Supply

This item is brand-new, factory sealed.

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 industrys first three-phased advanced thermal control to achieve optimal balance between silence and cooling.


80 PLUSPlatinum
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.


Compact Size
This ultra-high power density, small footprint (140 mm depth) power supply is an ideal choice for all, especially compact ATX cases.


Hybrid Silent fan Control
The industrys 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 of this design
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.
