Seasonic CORE GX-850 V2 White 850W 80 Plus Gold PSU, ATX 3.1, Full Modular, PCIe 5.1 - SRP-CGX851-A5A32SF-WH

Seasonic CORE GX-850 V2 White is a mid-range to high-end power supply with a power of 850W, aimed at serious gaming and workstation configurations, including modern graphics cards. It comes with an 80+ Gold certification and declared up to 90% efficiency, which means less heat loss and more stable operation. The power supply is ATX 3.0/3.1 and supports PCIe Gen 5.0/5.1, so you are ready for current and next-generation GPUs. The white color makes it particularly suitable if you are aiming for a clean, bright look for the case without relying on RGB effects.

What you get

With 850W real power and Active PFC, you have a stable power supply for systems with powerful CPUs and GPUs, without worrying about sudden drops or instability under load. The full modular design allows you to connect only the necessary cables – better airflow, cleaner build, and easier cable management. Thanks to the PCI-E Gen5 12VHPWR connector, you can directly power a modern high-end GPU without additional adapters, and the three PCI-Express 6+2 pin connectors provide flexibility for older or mid-range cards, including multi-GPU scenarios. With 6 SATA and 3 Molex connectors, you can easily connect several SSDs/HDDs, fans, or additional devices without running out of lines.

• Power 850W – sufficient for modern gaming and workstation configurations with powerful GPUs and many peripherals.
• 80+ Gold and up to 90% efficiency – lower consumption from the outlet, less heat, and quieter operation under typical load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 – fully ready for the new generation of graphics cards and stricter requirements for peak loads.
• Full modular design – all cables are detachable, making it easier to organize inside the case and improving airflow.
• PCI-E Gen5 12VHPWR x1 + PCI-E 6+2 pin x3 – combines direct support for the latest GPUs and flexibility for older cards.
• 6 SATA and 3 Molex connectors – enough power for multiple SSDs/HDDs, controllers, fans, and other accessories.
• Compact ATX format 140 x 150 x 86 mm with 120mm fan – standard installation and balanced cooling in most mid and full tower cases.
• White color, without RGB lighting – looks good in light builds and is aimed at a clean, minimalist appearance without a light show.

Who it is suitable for

This power supply is very suitable if you are building a serious gaming PC or productivity machine with a powerful GPU and want readiness for PCIe Gen 5, without entering the overkill territory of kilowatt+ PSUs. It is also suitable for white builds where aesthetics matter, but you do not care about RGB. If you are making a super budget system or a small ITX build, this PSU may be too powerful and large for your needs.

The combination of 850W power, 80+ Gold efficiency, ATX 3.1 with PCIe Gen5 12VHPWR, and modular design makes Seasonic CORE GX-850 V2 White a very balanced choice for a long-term, modern, and clean-looking build.
