PRIME Gold Series
The Seasonic PRIME Gold 850-watt power supply is fully modular and built with high quality components. Top-grade high-temperature capacitors provide ultra-low resistance and copper plates replace wiring to further improve power efficiency. This unit boasts an impressive 0.5 % tolerance fo load regulation, which protects the components against damage emanating from power fluctuations. Innovative fan control system gets paired with a top quality Fluid Dynamic Bearing Fan to lower temperature and noise. This power supply is a great choice for anyone who appreciated a high quality power supply with an impressive electronic performance.
80 PLUS® Gold
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 line-up 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.
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.
FDB: 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.
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 favourable 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 % (1% for 1000 W and above) load regulation. This impressive electrical performance and stability makes this power supply an ideal choice for high-performance systems.
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.
Our power supplies are equipped with 6-pin and 8-pin PCI-E connectors to support all GPU platforms.
Gold Plated Connectors
Gold plating critical connector pins (motherboard, CPU and PCIe cables) extends the lifetime of the connectors and greatly increases the efficiency of current transmission.
10 Years Warranty
Our commitment to superior Seasonic quality.

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.
Date Issued: 18th Nov 2010
Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.
