Seasonic Focus GX-850 V4 ATX 3.1 Gold 850W Power Supply White
Continuing the proven tradition of the Seasonic FOCUS series, the FOCUS GX series has been updated to meet ATX 3.1 and PCIe 5.1 standards. Fully modular cable management 80 PLUS Gold energy certification ATX 3.1 and PCIe 5.1 Less noise without increased temperatures Longer fan life due to lower speed Optimal heat dissipation at all times, further improved by the OptiSink technology. Unsurpassed silent running in fanless mode The new OptiSink design of the Seasonic FOCUS V4 series improves quality and reliability with a new PCB layout and automated SMT production. Smaller MOSFETs and heat sinks create more interior space, which significantly increases airflow and heat dissipation. Up to eight times better cooling for lower temperatures, longer service life and more efficient operation. In addition, the power supply unit can be operated safely in any orientation. The design is also more environmentally friendly and reduces material, production and long-term energy costs.
