Seasonic FOCUS power supplies form a separate family of modular and semi-modular models with power from 550 to 1000 watts. They occupy an average position in the "golden" Seasonic model range — between the relatively low-cost CORE series and the flagship PRIME.

Why are they interesting from a technical point of view? Seasonic names several key advantages. Firstly, it is an efficiency of at least 90%. The quality is confirmed by 80+ Gold and 80+ Platinum certificates (note: only the FOCUS PX model has it). Secondly, it is a flagship filling and a top-end element base, which includes proprietary circuitry, Japanese high-temperature capacitors and individual radiators on the hottest circuits. Such a gentleman's set allows FOCUS power supplies to easily cope with maximum consumption, ensure low ripple levels and work stably even when overloaded on the main line.


It is also important to mention that Seasonic, along with Be quiet, is one of the rare manufacturers of silent power supplies, and the FOCUS models perfectly emphasize this trend. Their cooling systems use unusual hydrodynamic bearings FDB, which we have seen in the flagship products of the brand. With a weak load in the region of 30%, the turntable may not rotate at all, without making a single sound, and at peak load the noise level does not exceed 22-23 dB, which makes it possible to record them, if not in the category of silent, then at least very quiet.

The fun doesn't end there. You may have heard about quality certificates and Japanese capacitors more than once or twice, this will not surprise anyone. The FOCUS series has an additional trump card. Seasonic is so confident in the quality of its products that they give a 10-year warranty on most models of this series. Even the most affordable model of this FOCUS GM series has an official warranty of 7 years.
