Focus GX ATX 3 Series Following the well-established legacy of the Seasonic FOCUS Series, the FOCUS GX Series has been upgraded to comply with the ATX 3.1 and PCIe 5.1 standards. It offers a complete range of power supplies from 750W to 1000W, all within a compact 140mm depth. Each unit features a 135mm fan, a 12V-2 6 cable, and our new OptiSink technology. These units are designed to be perfect allies in powering the latest high-power graphics cards and processors available on the market. Digital Hybrid Fan Control Operating in Fanless, Silent, and Cooling modes, this power supply intelligently shifts to deliver the right amount of power to your components when needed. At a whisper-quiet 20 dB, it suppresses noise levels without any rise in temperature, simultaneously extending its lifespan by monitoring unnecessary rotations. Ice Cold with Improved OptiSink Seasonic have flipped their PCB layout, improved their surface mount technology and included a smaller MOSFET, meaning the space within is increased to allow for a larger heatsink and more generous airflow space. This means cooling is better than it ever has been, and reliability is extended. Moreover, it allows for more eco-friendly manufacturing, requiring less materials and production.
