Its ultra-high efficiency and outstanding performance are the fine results of Seasonic’s continuous commitment to innovation and advancement. Improved low-load efficiency, highly suppressed ripple noise and a generous 12-year manufacturer’s warranty are just some of the characteristics that set these series apart from other power supplies on the market.
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.
The Cybenetics rating badge testifies that the PRIME Titanium 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. (About Cybenetics)
The noise output of the power supply is as good as it can be; the PRIME Titanium Series deserved the LAMBDA Noise Level A++ rating as its noise output stays below 20 dB(A) during operation. (About Cybenetics)
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.
Seasonics new PRIME 750W Titanium power supply excelled in every way during our testing. We opened this review by stating that the Prime 750W Titanium is the best power supply we have tested to date. (Read full review)

Technically it is difficult to find anything to fault. The Titanium rated power supply excels in load regulation and ripple suppression, hitting a top 2 of units we have tested in the last year. (Read full review)
In fact, the PRIME 750W did so well that calling it a great power supply might just be an insult. (Read full review)
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.
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.
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.
