In the range of 600W to 850W , with excellent electrical characteristics, top-level components, full modular cabling, made with industrial components and zero PCB cabling, go through rigorous testing to ensure the amazing load regulation and prolong hold-up time…

Features

General circuit design and component improvements render the Seasonic PRIME series the best performing and the quietest analogue power supply on the market.

PG hold-up time measured under 100 % load is increased from an industry standard of 16 ms to above 30 ms

Instead of cables, the back panel and the PCB are connected by a copper plate. This design not only improve the overall layout, but also reduces the chance of production errors during manual insertion.

The industry's first, advanced three-phased thermal control finds perfect balance between silence and cooling :Fanless, Silent and Cooling Mode. Users can manually select between the Seasonic S2FC (fan control without Fanless Mode) and S3FC (fan control including Fanless Mode). This unit has a built-in fan control IC, which utilizes hysteresis to optimize how frequently the fan switches on and off. Seasonic’s vast experience in designing the most silent power supplies on the market was translated into the development of a state-of-the-art fan control to keep the overall fan noise at a lowest possible.

The Seasonic PRIME 80 PLUS® Titanium certified power supply is rated to achieve 94 % efficiency at 50 % system load.

Ultra-High Efficiency, 80 PLUS® Titanium Certified

The PRIME 80 PLUS® Titanium achieves the highest level of 80 PLUS® Titanium certification on the market with its 94% efficiency at 50 % system load.

Micro Tolerance Load Regulation

Seasonic’s latest design keeps the output voltage within a very tight range, achieving under 0.5 % load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.

Top-Quality 135 mm Fluid Dynamic Bearing (FDB)Fan

The high-pressure oil between the FDB's drive shaft and bearing sleeve reduces friction and vibration to increase product lifetime and reliability. The 135 mm larger-sized fan allows for reduced fan rotation speed while maintaining optimal cooling.

Premium Hybrid Fan Control

Seasonic’s vast experience in designing the most silent and efficient power supplies on the market was translated into the development of Hybrid Mode; a state-of-the-art fan control that enables users to keep the overall fan noise at the lowest possible level.

Super Low Ripple Noise (Under 20mV)

Seasonic’s continued commitment to excellent analog power supply design has suppressed ripple noise to fall well below the current industry average of 20 mV.

Extended Hold-up Time (above 30 ms)

Improved circuit design and high-quality components have greatly increased the hold-up time measured under 100 % load, from an industry standard of 16 ms to above 30 ms. This substantial improvement means that even under unstable input current conditions the power supply will continue to output stable and precise current to ensure smooth operations.

Highly Reliable Aluminum Electrolytic Solid Capacitors

Top-grade, Japan-sourced components extend product life and ensure operation stability under extreme conditions.

Cable-free Connection Design

Seasonic’s engineers have implemented a new design feature, where instead of cables, the back panel and the PCB are connected by a copper plate.This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality.
