An advanced-level power supply unit that stands out due to its high power reserve of 850W, 80+ Gold certification, and support for ATX 3.1 and PCIe 5.1 power standards, which were announced in 2024. The PSU is built on modern circuitry, with key components being thermally resistant Japanese-made solid capacitors with a thermal rating of 105°C. According to the manufacturer, even under constant maximum load on the power line, the internal component temperature does not exceed 50°C.
The official warranty period is 10 years, placing this model in line with more advanced platinum and titanium level power supplies. The power supply is equipped with a fully modular cable connection system. For cooling, a large 140 mm fan on a hydrodynamic bearing is used. Users can independently adjust the fan speed and noise level using a mechanical controller located on the rear panel.

Purchased in June 2025, at that time I had a Ricsa 6600, nothing special, 8 pin power. A month later, I bought a 5070ti and decided to power it through 12v 6x2, everything worked, but!!!! As soon as I started loading a game, the computer rebooted... (I inserted the connector all the way in, so there can't be a mistake here) I thought it might be the system, maybe a driver conflict, maybe I deleted something using DDU when I was cleaning the system from an AMD driver. But I remembered that this can happen when there's not enough power for the video card, when capacitors are bloated.
I decided to try the included adapter that came with the video card, and everything started working)))
