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.


Fan Type Fanless-01 

Fanless

Cooling fans inside the power supply are replaced by passive cooling based on heat dissipation. Silent operation does not only provide a more pleasant working environment but it also results in less power consumption and lower utility bills.


Japanese Capacitor-01

105 °C Japanese Capacitor

Premium quality Japanese capacitors with 105 °C rating increase overall reliability and extend product life.


7 Years Warranty-01

7 Years Warranty

Our commitment to superior Seasonic quality.


DC to DC Converter Design-01

DC to DC Converter Design

The step down DC to DC converter design allows the power supply to be able to serve system components with various voltage needs. Not only is it a flexible, clean voltage conversion solution but it also maximizes the 12 V DC rail output, delivers superior dynamic response and , ultimately, provides for greater system stability.


Modular Cables-01 

Fully Modular Cables

In Sea Sonic’s patented design feature full modularity comes hand-in-hand with the extensive use of SMD technology to increase the overall performance and reliability of this power supply. The simple and inventive layout scheme helps to attain unsurpassed quality and performance, where efficiency is further enhanced by minimized line resistance, reduced voltage drop and lower impedance. Reduced component count and better space utilization facilitate optimal air flow inside the case and promote heat dissipation, proper cooling and ultimately longer product life.

“This is not the first time that a Seasonic product manages to amaze me and it surely won’t be the last! The new fanless Platinum 520 W unit is a great performer with ultra-stable rails that deliver very clean outputs. Your choices are pretty limited if you are looking for a fanless PSU, especially if you seek a Platinum efficiency one. The Seasonic SS-520FL’s platform easily allows this unit to confront and eclipse its competition by providing top performance for a price that beats every other fanless Platinum PSU out there, which makes its purchase a no-brainer.”
