PRIME PX

Pressing on with its One Seasonic Initiative, the PRIME TX, PRIME PX and PRIME GX series became the successors to the Seasonic PRIME and PRIME Ultra series.

The PRIME Series has always demonstrated outstanding performance and have become the epitome of technological excellence and quality through the years. This third generation of PRIME Series rolled out not only with a uniformed naming scheme but also with updated general design and connection cables. As each new model in these PRIME series have their distinctive set of features and specifications, prospective customers will find a streamlined buying guidance through understanding the One Seasonic process.

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.

  • 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.

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.

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.

Recommended Installation of 12VHPWR Cable

  • BOTH 8-pin connectors must be plugged in at all times to your power supply.
  • All connectors must be correctly INSERTED, CLICK-LOCKED and TIGHT.
  • DO NOT bend or apply force to the cable after it is plugged into place.

12VHPWR Cable

FOR PRIME PX-1000 & 1300:

As we continue to improve and update our products, we recently added a 12VHPWR cable to the cable set. Kindly note, during this transition period customers may purchase power supplies that are either with or without this 12VHPWR cable. We apologize in advance for the inconvenience.

FOR PRIME PX-1600:

The Seasonic PRIME PX Series power supplies have initially been delivered with two 12VHPWR cables with braided sleeving. Responding to feedback from end users, we have started replacing these with braid patterned cables. During this transition period customers may receive either one of these two types of 12VHPWR cables in the box. We are sorry for the inconvenience.
