Seasonic 850W X-850 Power Supply - ATX12V, 80PLUS Gold

Seasonic 850W X-850 Power Supply - ATX12V, 80PLUS Gold

During the recent past, there have been a growing number of high-end systems builders looking for efficient and reliable power supplies in the higher power output ranges. This top-class power supply is able to deliver a complete package of ultra-high efficiency, superb dynamic response, and customizable cable arrangement that can be tailored to meet all specific needs. Sea Sonic stands behind the excellent build quality of this product by extending its customers worldwide a generous 7-year manufacturer’s warranty.

80 PLUSGold

Seasonic was the forerunner of creating the very first 80 PLUS Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency. The highly efficient 80 PLUS Gold certification guarantees greater than 87 %, 90 % and 87 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The clear advantage of buying a power supply with 80 PLUS Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.

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.

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).

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.

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.

105 °C Japanese Capacitor

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

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.
