SEASONIC Prime TX-1300 ATX 3.1 1300W Power Supply
PRIME TX ATX 3.1
The Seasonic PRIME TX ATX 3.1 Series is built on top of all the great features of PRIME TX platform with added ATX 3.1 and PCIe 5.1 compatibility. Currently the 1600 W and 1300 W units are equipped with native 12V-2×6 connectors, Digital Fan Control, and 105°C-rated Japanese electrolytic capacitors guarantee unwavering power delivery and long-term durability. All these qualities make these power supplies perfect to welcome the newest high power graphic cards and processors on the market.
80 PLUS® Titanium Certified
ATX 3.1 and 16-Pin PCIe Gen 5 Cable (12V-2x6)
Seasonic’s latest PRIME ATX 3.1 Series is designed and built to power new PC components requiring the new ATX 3.1 and PCIe 5.1 standards.
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.
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.
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.
