The SeaSonic Focus GX-850 ATX 3.0 PSU Review: Cool, Quiet, and Robust

In the realm of power supply units (PSUs), the core underpinning of any high-performance computing system, seasoned market players have continually raised the bar in delivering efficient, reliable, and technologically superior products. One such stalwart in the PSU domain is SeaSonic, whose meticulous engineering and innovation have repeatedly set industry benchmarks.

In today’s review, we are having a look at the ATX 3.0 upgrade of SeaSonic’s revered Focus series, which epitomizes a fine balance between cost and performance aimed at catering to a broad spectrum of PC enthusiasts and builders. It is the successor of the Focus Plus series, which used to be SeaSonic’s most popular series over the past several years.

The new Focus GX series consists of five units with a power output ranging from 550 Watts to 1.000 Watts. It is the second most powerful unit of the series that we will be putting to the test, the Focus GX-850. SeaSonic is placing its marketing efforts mostly on the exceedingly long 10-year manufacturer’s warranty, its compact size, the 80Plus Gold efficiency certification, and the modular design.
