Power supply Seasonic CORE GX White 850W 80 Plus Gold, Fully Modular, ATX 3.1, PCIe 5.1

Seasonic CORE GX White 850W is a power supply from the higher mid-range class, aimed at serious gaming and workstation configurations with powerful GPUs and plenty of storage. You have 850W of power and 80+ Gold certification, which means high efficiency and lower consumption compared to more budget solutions. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 covers you for modern and future graphics cards. The white chassis makes it a logical choice for builds with a light theme, without unnecessary RGB lighting.

What you get

With 850W, you can comfortably power a powerful CPU and high-end GPU, plus several SSDs/HDDs and peripherals, without worrying about a power supply bottleneck. 80+ Gold and up to 90% efficiency mean less loss as heat and lower fan noise under typical gaming or workload. The support for 12V-2x6 PCIe connector (part of the ATX 3.1 / PCIe 5.1 specification) allows direct connection of modern graphics cards without adapters. The numerous SATA and Molex connectors give you the freedom for more drives, controllers, or fans. Active PFC helps for more stable power supply and better performance during fluctuations in the network.

• Power 850W – sufficient for a strong gaming or workstation build with a powerful graphics card and many additional components.
• 80+ Gold certification and up to 90% efficiency – lower consumption from the outlet, less heat, and quieter operation under typical load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – readiness for modern and future GPUs according to the current power supply standard.
• 1 x 12V-2x6 PCIe connector – direct power for new graphics cards without the need for additional adapters.
• 2 x PCI-Express 6+2-pin and 2 x 4+4-pin ATX/EPS – flexibility for powering different GPU configurations and more serious motherboards with more powerful CPUs.
• 6 x SATA and 3 x Molex – enough connections for SSDs, HDDs, fans, controllers, and other accessories.
• 120 mm fan – standard size for better balance between cooling and noise during everyday use.
• Active PFC – more stable operation and better compatibility with the electrical network over a wide range of 100 - 240 VAC.
• ATX form factor and white color – easy installation in standard cases and a clean, light look for a white build without RGB.

Who it is suitable for

This power supply is suitable if you are building a serious gaming or productive computer with a modern graphics card and want to be covered for the ATX 3.1 / PCIe 5.1 standard. It is ideal if you are aiming for a white aesthetic build and are not looking for RGB synchronization. If you are making a very budget machine or an ultra-compact build, the 850W ATX block may be too much in size and capacity.

The most sensible aspect here is the combination of 850W, 80+ Gold efficiency, and ATX 3.1 / PCIe Gen 5.1 in a white case – a ready solution for a modern, clean, and stable high-performance computer.
