Power Supply Seasonic CORE GX-850 V2 850W 80 Plus Gold ATX 3.1 PCIe 5.1 - SRP-CGX851-A5A32SF

Seasonic CORE GX-850 V2 is an 850W modular ATX power supply from the upper mid-range class, which easily handles modern gaming and work configurations. It features an 80+ Gold certification and up to 90% efficiency, meaning less loss and lower temperature under load. The power supply is compliant with the latest standard ATX 3.0/3.1 with PCIe Gen 5.0/5.1, so you are ready for the new generations of GPUs. The black design and modular cables give you a clean and organized build without unnecessary bundles.

What you get is a stable 850W platform with Active PFC and input from 100 - 240 VAC, so it works without drama at different mains voltages. The modular design allows you to install only the necessary cables – less cable chaos and better airflow in the case. With the combination of PCI-Express 6+2 pin and PCI-E Gen5 12VHPWR, you can power both older and completely new generation graphics cards. A 120mm fan takes care of cooling without interfering with excess noise during normal operation. The availability of sufficient SATA and Molex connectors gives you flexibility for drives, fans, and peripherals.

• Power 850W – suitable for strong gaming configurations with one high-end GPU and powerful CPU, without risking power shortages.
• 80+ Gold certification and up to 90% efficiency – less loss as heat, lower consumption from the outlet, and lighter load on cooling.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – fully compatible with the latest graphics cards and requirements for sudden peak loads.
• PCI-E Gen5 12VHPWR x1 + PCI-Express 6+2 pin x3 – flexibility to power modern and older GPUs without the need for dubious adapters.
• Modular power supply – you connect only the necessary cables, improving airflow and facilitating cable management in the case.
• 6 x SATA and 3 x Molex connectors – enough for SSDs, HDDs, fan hubs, and additional accessories in the system.
• Active PFC and input 100 - 240 VAC – more stable operation under fluctuations in mains voltage and better power factor correction.
• 120mm fan and black ATX format – standard size for easy installation, with a simple black design without RGB, if you are looking for a cleaner look.

Who it is suitable for: if you are building a serious gaming or work build with one more powerful GPU and want to be ready for PCIe Gen 5, this power supply is a logical choice. It is also suitable for upgrading an older system where you plan to change only the graphics card to a newer generation. If you are aiming for extreme multi-GPU or heavily overclocked configurations, you may benefit from an even higher class and power.

The combination of 850W power, 80+ Gold efficiency, and ATX 3.1 with 12VHPWR makes this power supply a very balanced choice for today’s and tomorrow’s gaming configurations. You get a stable platform with modular cables and real readiness for the new generations of hardware.
