Overview
Seasonic
Seasonic PRIME PX: High quality 80+ Platinum third generation power supply
The Seasonic PRIME PX features 80+ Platinum certification, a 100% modular design and allows fanless operation below 40% load. It features a quiet 135mm fan and its rich connectivity allows it to power a configuration with the most powerful components with a reliable and stable voltage.
Featuring the latest technological advances, the PRIME PX maintains the output voltage within a very tight range, achieving load regulation of less than 0.5% (MTLR). This impressive power performance and stability make this power supply an ideal choice for high performance systems.
FDB Fan
The 135mm high performance fan in this power supply is designed to take advantage of the impact absorption effects of oil. It is extremely reliable and generates much less operating noise and heat than ball-bearing fans. Lubrication of the bearing surface reduces friction and vibration, thus reducing overall energy consumption. Due to the effortless and quieter rotations and the robust construction, this proven fan technology also increases the life of the fan.
Hybrid cooling
This Seasonic PRIME power supply features the Premium Hybrid Fan Control system, which minimises the noise generated by the fan. Below 40% load, the unit is in 0dB (fanless) mode and then the fan turns on in proportion to the load of the configuration.
Internal cable-free design
Seasonic engineers have implemented a new internal design, where instead of cables, the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This solution not only reduces the risks during assembly, but also improves the quality and reliability of the power output.

Good nutrition
Seasonic true to its reputation, good power supply, many cables provided.
However, I find the cables a little bit fake (plastic and 6+2 pin adapter "to assemble" for PCIe). The latter are not very aesthetic, which in my opinion deserves 9/10.Review automatically translated -

First purchase of this brand
And I am not disappointed. No more wires running around with this fully modular power supply. The connections are perfect. The power supply is silent and you can even put it in fanless.
For now, the power supply behaves very well. We'll see on the long run.Review automatically translated
