Power Supply Seasonic FOCUS-GX-850-V4-WHITE 850W 80 Plus Gold ATX 3.1 PCIe 5.1

Seasonic FOCUS-GX-850-V4-WHITE is an 850W ATX power supply from the higher mid-range class, aimed at modern configurations with current GPUs from the PCIe Gen 5 generation. It combines 80+ Gold certification, 90% efficiency, and support for ATX 3.1 / PCIe 5.1, so you can be confident about consumption and peak loads. The white color and individual braided cables make it particularly suitable for showcase cases with a transparent panel. This is a power supply that is both quiet, modern, and visually appealing.

What you get

With a power of 850W and Active PFC, you have sufficient resources for both a strong gaming build and a workstation with a more serious GPU. The PCI-E Gen5 12VHPWR connector allows you to power modern graphics cards with a single cable, without the need for adapters, while the three PCI-Express 6+2 pin provide flexibility for an older or second GPU. The large 135mm FDB fan and Digital Hybrid Fan Control ensure very quiet operation and fanless mode under low load, which is a plus for a quiet machine. The fully modular design and individual white braided cables facilitate cable management and give a clean, premium look to the interior.

• 850W power – sufficient for high-end CPU and modern GPU, without worrying about power shortages during serious gaming or rendering.
• 80+ Gold and 90% efficiency – less loss as heat and lower power consumption at identical loads compared to lower-class PSUs.
• ATX 3.1 and PCIe 5.1 compatibility – ready for the latest generation of graphics cards and their transient peaks, without relying on adapters and compromises.
• PCI-E Gen5 12VHPWR + 3 x PCI-Express 6+2 pin – a flexible combination of connectors for current and future GPU configurations.
• 8 x SATA and 3 x Molex – enough connections for SSDs, HDDs, fans, and peripherals in more serious builds with many devices.
• Fully Modular design – you connect only the necessary cables, which improves airflow and facilitates maintenance and upgrades.
• 135mm FDB fan with Digital Hybrid Fan Control – very quiet operation and fanless mode under low load for almost silent idle.
• White casing and individual white braided cables – a visually appealing choice for white or themed builds without the need for aftermarket cables.

Who it is suitable for

This power supply is suitable for serious gaming and creator configurations that aim for stability and readiness for new PCIe Gen 5 graphics cards. It fits particularly well with white or showpiece builds with a transparent panel, where the visual aspect is as important as stability. If you are building a super budget PC or a micro build with another form factor, this may be more than you need in terms of capabilities.

The strongest combination here is the combination of ATX 3.1 / PCIe 5.1 support, 80+ Gold efficiency, and fully modular white design with a quality quiet fan – a ready solution for a modern, clean, and reliable build.
