well advised
the 1st power supply didn't work, so we returned it. The second works well. Good advice before the sale and good follow-up with the customer service. I recommend LDLC.

Overview
A high-level hybrid-cooled power supply
Built with quality components, this Seasonic FOCUS GX Gold power supply will always provide impeccable voltage and outstanding reliability for long term use. This highly efficient unit incorporates an innovative fan control system that allows the fan to not start at low load and only start when the temperature requires cooling. If you want the fan to be always on, simply press the hybrid mode button on the back of the power supply. Fully modular, it allows for a clean, customisable installation while helping to improve internal airflow.
Hydrodynamic Bearing Fan (FDB)
High performance hydrodynamic bearing fans (FDB) are designed to take advantage of the impact of oil absorption effects. They are extremely reliable and generate much less noise and heat during operation than ball bearing fans. Lubrication of the bearing surface reduces friction and vibration, which also reduces the fan's overall power consumption. With smoother, quieter rotation and quality construction, this highly reliable technology also increases the life of the fan.
As the fan shaft rotates, high-pressure oil spreads along the grooves in the bearing sleeve to create a thin layer of lubrication on the ball bearing. As the speed increases, so does the dynamic pressure of the oil. The fan shaft then lifts off the bearing to rotate effortlessly. The herringbone shape of the grooves ensures that the lubricant is channelled effectively and thus prevents leakage.
Hybrid fan control for more silence
Seasonic 's vast experience in developing the most efficient and quietest power supplies on the market has been translated into the development of Hybrid Mode; a state-of-the-art fan control that allows users to keep noise levels as low as possible.
The latest Seasonic platform keeps output voltages within a very tight margin with less than 0.5% variation under load. This impressive performance and electrical stability makes this power supply the ideal choice for all high-performance machines. In addition, the Seasonic Prime series is designed with a reduced acoustic signature to reduce operating noise.
80PLUS Gold certification and cable-free design
Seasonic 's FOCUS GX Gold Series achieves 80PLUS Gold certification with 90% efficiency at 50% system load.
Seasonic 's ongoing commitment to developing quality analog power supplies has resulted in ripple levels well below the average industry standard of 20mV. Seasonic engineers have implemented a new internal design where, instead of cables, the backplane and PCB (Printed Circuit Board) are connected by a copper plate. This advance not only reduces the chance of production errors during the manual manufacturing phases but also improves the quality of the output voltages...

Seasonic quality
Very good quality power supply, with enough cables for a complex PC (lots of disks, large graphics card).
Initially I'd chosen a Corsair power supply but it was too long for my case (Fractal Design Core 500) and it turns out that my new case (Fractal Design Pop Air) wouldn't have had enough space. The Seasonic power supply, on the other hand, has more reasonable dimensions which should fit all cases.
I was a bit worried that 850W wouldn't be enough to power a radeon 7900XTX and a ryzen 5800X3D but after two weeks of intensive testing it seems to be holding up!
I've been using it practically every day for 4 years, and I have no regrets.Review automatically translated -
