SEASONIC FOCUS GX-850 850W White 80 Plus Gold PCIe 5.0, Fully Modular - SSR-850FX3-W

Seasonic FOCUS GX-850 850W White is a high-end ATX power supply aimed at modern gaming and workstation configurations with a powerful GPU. With 850W power and 80+ Gold efficiency certification, this PSU is fully prepared for serious hardware. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 and the presence of a 12VHPWR (12+4) Pin connector make it a suitable choice for the new generation of graphics cards. The white color makes it particularly suitable for builds with an open panel and a focus on aesthetics.

What you get

With 850W you have enough headroom for high-end CPU and GPU combinations, without worrying about stability during peak loads. The 80+ Gold certification and stated 90% efficiency mean less energy loss as heat and lower power consumption during long gaming sessions or rendering. The modular design allows you to connect only the necessary cables, which simplifies cable management and improves airflow in the case. The large 135mm FDB fan is designed for quieter operation and better cooling of the components inside. Thanks to the active PFC and wide input range 100 – 240 VAC, the power supply handles variations in mains voltage more stably.

• Power 850W – suitable for configurations with powerful graphics cards and many additional components, without the risk of power shortage.
• 80+ Gold certification and around 90% efficiency – less energy loss as heat and lower electricity bills during prolonged use.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – ensures compatibility with the latest generations of GPUs and better resilience during sudden peak loads.
• 1 x 12VHPWR (12+4) Pin connector – direct power for modern graphics cards without the need for adapters.
• Modular design – all cables are separate, so you only use the necessary ones and keep the interior of the case tidy and well-cooled.
• 135mm FDB fan – quieter and smoother operation compared to standard fans, with better durability for long-term use.
• Rich connector set – 3 x PCI-Express 6+2-pin, 2 x CPU 4+4 Pin, SATA (including SATA 3.3V) and Molex cover the needs of most gaming and workstation configurations.

Who it is suitable for

This power supply is suitable for gamers and enthusiasts planning a build with a new generation graphics card and want headroom for future upgrades. It is also a good choice for content creators with powerful CPUs and multiple drives who prioritize stability and efficiency. If you are making a very budget build with a weaker GPU, 850W may be excess capacity.

The combination of 850W power, 80+ Gold efficiency and ATX 3.0 / PCIe 5.0 readiness in a fully modular, white case makes this PSU a very balanced choice for a modern, powerful, and visually complete computer.
