The Seasonic PRIME PX 3.0 Series is built on top of all the great features of PRIME PX platform with added ATX 3.0 and PCIe 5.0 compatibility. Currently the 1600 W is equipped with native 12VHPWR connectors and Digital Fan Control, and 105°C-rated Japanese electrolytic capacitors guarantee unwavering power delivery and long-term durability. All these qualities make this power supply perfect to welcome the newest high power graphic cards and processors on the market. 80 PLUS® Platinum
The PRIME PX Series achieves 80 PLUS® Platinum certification with its 92 % efficiency at 50 % system load.
ATX 3.0 and 16-Pin PCIe Gen 5 Cable (12VHPWR)
Seasonic’s latest PRIME ATX 3.0 Series is designed and built to power new PC components requiring the new ATX 3.0 and PCIe 5.0 standards.
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.
Digital 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 digital fan control that enables users to keep the overall fan noise at the lowest possible level.
Note: The Digital Hybrid Fan Control chart is provided for reference only. The shape of the curve can look different due to the variability in ambient temperature, system set-up, air flow, and other unpredictable factors.
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.
