Official BP. The equipment is generally royal, bags, boxes, sachets)) To be honest, I did not expect this from a PSU for 120 bucks. The wires are long, those for additional power are also separated (6 + 2 or 8) All in an iron braid, in short, I'm delighted). What is the button to disable or enable passive cooling. I didn't know about this at all. I measured the efficiency (output) in the load, it turned out 88% when applying 500 watts! It is not audible at all at low and medium loads, at high it is audible, but weakly. Doesn't overheat. I looked at the layout under the set, everything is very neatly done. I found a disassembled photo on the Internet, everything is on Japanese spare parts, almost all polymer capacitors. There is also a sense of heaviness. and something noble. I put it in the computer and I’m 100% sure that it will plow for more than one year. I hope my review will help someone decide, but I'm very pleased. The workmanship is top notch. Good fit and attention to detail. Long cables + separated by pins. Excellent efficiency. Quiet. No  Anton Ch: use Seasonic FOCUS GX-550 few months |

It's too early to evaluate. a couple of months in the work. but the supply is really rich. all in bags. the turntable is quiet. module .plus version was with tester.

Efficiency 90%
For several decades, Seasonic has been a leading innovator in the computer power supply market. It was this company that introduced innovations such as automatic fan speed regulation based on temperature, Active PFC power correction, and 80 PLUS Gold energy efficiency certification. Seasonic continues to maintain its momentum today. The newest Focus Plus lineup continues the traditions of Seasonic's "gold" power supplies, built on their own OEM platforms, offering flagship modular models with an 80 Plus Gold certificate, a high-quality component base, and a range of interesting technical features.
Quiet and stable operation under maximum load
So, the Sea Sonic Focus Plus Gold is a fully modular power supply (all cables can be detached, including motherboard and processor power) with a capacity of 550W and an 80+ Gold certification (Efficiency 90%). Inside the Sea Sonic Focus Plus Gold is circuitry of their own design, exclusively Japanese high-temperature capacitors, and several large heatsinks on the hottest circuits (while other PSUs have only one or two small heatsinks). Thanks to the quality circuitry, this model easily handles maximum consumption and can operate with noticeable "overload."
10-Year Warranty
The cooling system fan is based on an innovative FDB hydro-dynamic bearing, which is also used in Seasonic's higher-end models. It operates almost silently even under maximum load on the PSU, and at less than 30% load, it might not spin at all. The company is so confident in the quality that they offer 100,000 hours of bearing assembly lifetime and a 10-year warranty on the power supply itself. Compare this to the standard 12 to 24 months offered by most competitors. Considering all this, calling this model expensive doesn't seem right; every penny spent is fully justified.
