Seasonic FOCUS GX FOCUS GX-550 (SSR-550FX)

Efficiency 90%

For decades, Seasonic has been a major innovator in the computer power supply market. It owns such know-how of its time as automatic regulation of the PSU fan speed depending on temperature, Active PFC power correction and 80 PLUS Gold energy efficiency certification. Seasonic does not slow down even now. The latest Focus Plus line continues the tradition of Seasonic's "golden" power supplies built on its own OEM platforms, offering flagship modular models with 80 Plus Gold certification, high-quality components and a number of interesting technical features.

Quiet and stable operation at maximum load

And so, Sea Sonic Focus Plus Gold is a fully modular (all wires are detachable, including motherboard and processor power) 550 W power supply with an 80+ Gold certificate (90% efficiency). Inside the Sea Sonic Focus Plus Gold is its own design circuitry, exclusively Japanese high-temperature capacitors and several large heatsinks at once on the hottest circuits (whereas other power supplies have only one or two small heatsinks). Thanks to high-quality circuitry, this model easily handles with maximum consumption and can work with a noticeable "overload".

10 year warranty

The fact is that the cooling system fan is based on the innovative FDB hydrodynamic bearing, which is also used in the older models from Seasonic. It works almost silently even under the maximum load on the PSU, and at a load of less than 30% it may not rotate at all. The company is so confident in the quality that they give 100,000 hours of bearing assembly life and a 10-year warranty on the power supply itself. Compare this to the standard 12 to 24 months given by most competitors. Considering all this, calling this model an expensive one does not turn your tongue, every penny spent here is as justified as possible.
