The Seasonic PRIME 80 PLUS Platinum certified power supply is rated to achieve 92 % efficiency at 50 % system load. This high efficiency ensures that there is less heat wasted during operation, which in turn not only reduces the strain on the system components but it also lowers the costs of electricity for users. An ultra-quiet, 135 mm Fluid Dynamic Bearing Fan (regulated by Seasonic’s proprietary Premium Hybrid Fan Control) delivers excellent airflow with exceptionally low noise levels. This unit is an ideal companion to an office computer or an environment where noise levels need to be at the minimum.
80 PLUSPlatinum
The higher the level of efficiency of the power supply, the less power gets wasted in the form of excess heat . The 80 PLUS Platinum certification guarantees greater than 90 %, 92 % and 89 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The Seasonic Platinum Series represents the highest level of technology and efficiency achievement of Sea Sonic during its 40 years of commitment to engineering excellence.
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.
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 % (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.
Multi-GPU Setup
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.
12 Years Warranty
Our commitment to superior Seasonic quality.
