80 PLUS® Titanium

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

Cybenetics ETA Efficiency Level A

The top-level Cybenetics rating badge testifies that the PRIME Titanium 850 operates between 91 % and 94 % efficiency at all times, at any load. The power supply achieves above 77 % efficiency on the 5 Vsb rail and it merely consumes less than 0.15 W when the system is idling. (See test report | Learn more about ETA)

Cybenetics LAMBDA Noise Level A++

The noise output of the power supply is as good as it can be; the PRIME Titanium 850 deserved the LAMBDA Noise Level A++ rating as its noise output stays below 20 dB(A) during operation. (See test report | Learn more about LAMBDA)

Fluid Dynamic Fan Bearing

High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.

How it works

When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
The following illustration depicts the main characteristics of the FDB fans:

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.

Power Supply Sound

The Seasonic PRIME Series is designed with very favorable level of acoustics and it uses carefully selected components and innovative circuit design to minimize sound output. Beyond our rigorous internal tests, the power supply also went through external testing with the most popular graphics cards to ensure that the sound at all loads would be kept at the lowest possible level. The chart compares the sound level of the Seasonic PRIME power supply to other ambient sounds.

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.

Extended Hold-up Time (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.

Super Low Ripple Noise (20 mV)

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.

Cable-free Connection Design

Seasonic’s engineers have implemented a new design feature, where instead of cables; the back panel and the PCB (Printed Circuit Board) 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.
