Platinum 660

The most popular member of the Seasonic Platinum product line is well known for its stability and reliable performance. This unit achieves extremely high power conversion efficiency with unbelievably tight (2%) voltage regulation. Like all Platinum series units, the Platinum 660 also comes outfitted with fully modular cables that offer flexibility during system build. The Seasonic patented Hybrid Silent Fan Control can be personalized with the help of a toggle switch, which allows users to select between the S2FC control (without Fanless Mode) and the S3FC fan control (including Fanless Mode). This power supply is a true definition of what genuine premium power supplies should be.

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 Sanyo Denki-01

Sanyo Denki Fan

The world-renowned Sanyo Denki ball bearing fans are made of the highest quality components to ensure ultra-low noise performance. The fan’s perfect balance and even rotations are achieved via the use of spoon-shaped, high-density plastic fan blades that are finished off with smoothed leading edges. Sanyo Denki fans are known for their strict tolerance ball bearings and precision copper axels. Instead of the industry standard of two balancing points they use three points to strengthen the mount and further stabilize the blade.


Fan Control S3FC-01

Hybrid Silent fan Control

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.

S3FC

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.

Additionally, there is a switch at the back of the power supply which allows users to customize their cooling needs by selecting between the Seasonic S2FC (fan control without Fanless Mode) and the S3FC (fan control including Fanless Mode).


Double Ball Bearing Fan-01 

Double Ball Bearing Fan

These durable power supply fans play an important part in the temperature control of the entire system by not only keeping themselves cool but also by removing warm air from inside the computer case. Coupled with Sea Sonic’s fan control circuit, double ball bearing fans are great performers, relatively quiet and have a very long life span.


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.


Stable Voltage Regulation-01 

Stable Voltage Regulation (2 %)

Improved voltage regulation stays well within Intel’s specifications to ensure smooth operation and protect all system components.

“…probably the best power supply we have reviewed overall. The PLATINUM-660 posts the best voltage regulation we have ever seen, close to the best efficiency we have ever seen, it is for all intents and purposes is silent compared to other components in a system, has outstanding DC Output Quality, absolutely excellent build quality, and even posts better Transient Load responses than we have seen in a long time from a unit of such a capacity. Perhaps the only way the Platinum-660 gets better is if Seasonic was giving these away! ”
