This article covers SAMA 850W ブラック電源、フルモジュラー80 Plus、Gold ATX 3.1およびPCIE 5.1認定、GPU RTX 30/40シリーズ互換.

Overview

The SAMA GT 850 Black is a fully modular 850W ATX power supply with 80 Plus Gold certification. It supports the latest ATX 3.1 and PCIe 5.1 standards, providing native compatibility with high-end GPUs like the RTX 30 and 40 series. Built with Japanese capacitors and backed by a 5-year warranty, it's designed for long-term reliability.

Key Features

  • 80 Plus Gold Efficiency: Up to 91.15% efficiency at 50% load, reducing power waste and heat output.
  • Fully Modular Cabling: Connect only the cables you need for cleaner builds and better airflow.
  • ATX 3.1 & PCIe 5.1 Ready: Native 12VHPWR connector eliminates the need for adapters with RTX 3090 Ti and RTX 40 series GPUs.
  • Quiet 120mm FDB Fan: Fluid dynamic bearing fan operates below 20dB(A) and includes an ECO mode for semi-passive operation.
  • Japanese Capacitors + 5-Year Warranty: High-quality components ensure stable power delivery and long service life.

Compatibility Guide

  • Form Factor: Standard ATX (150mm depth). Fits most mid-tower cases; check clearance in compact builds.
  • Connectors: ATX 24-pin, EPS 12V (CPU), PCIe 5.1 (12VHPWR), SATA, and peripheral connectors.
  • GPU Support: Works with all current RTX 30/40 series and future PCIe 5.0 GPUs.
  • Wattage: 850W is ideal for mid-high to high-end single-GPU systems (e.g., Core i7/Ryzen 7 + RTX 4070 or higher).

Ideal Builds

  • Gaming Rigs: Pair with an RTX 4070 Super or RTX 4080 for smooth 1440p or 4K gaming.
  • Creator Workstations: Stable power for video editing, 3D rendering, and other sustained workloads.
  • Silent PCs: The FDB fan and ECO mode keep noise to a minimum during light use.

Upgrade Considerations

  • Over-Spec Warning: For budget builds (e.g., RTX 4060 + Core i5), a 650W unit may suffice. The 850W is a future-proof choice if you plan to upgrade to higher-tier components later.
  • Case Clearance: At 150mm depth, it may not fit in some small form factor (ITX) cases. Always measure your PSU compartment before purchasing.
  • ATX 3.1 Future-Proofing: While not essential today, ATX 3.1 will likely become standard for next-gen GPUs, making this a smart long-term investment.
