ASUS TUF Gaming 850W Gold PSU – Fully Modular, ATX 3.1 & PCIe 5.1 Ready

Built For The Long Haul
The ASUS TUF Gaming 850W Gold is built for gamers, power users, and PC enthusiasts who demand stability, efficiency, and long-term durability. Armed with military-grade components, a 135mm Axial-tech fan with dual ball bearings, and full ATX 3.1 compliance, this PSU is engineered to support the latest hardware, including PCIe Gen 5.1 graphics cards.
Its 80 PLUS Gold certification ensures up to 92% efficiency, reducing heat, lowering noise, and minimizing energy consumption. Thanks to fully modular etched cables, cable management is easier and cleaner than ever. A conformal coating on the PCB protects against moisture, dust, and extreme temperatures, making this PSU ideal for tough environments.
Whether you’re powering a high-performance gaming PC or a future-ready workstation, the TUF Gaming 850W Gold is a reliable, long-lasting power supply unit backed by an impressive 10-year warranty.
Performance and Specifications
High-Performance Copper Pins
Upgraded PCIe® connectors featuring superior thermal conductivity ensure cooler operation and improved power delivery efficiency.
This translates to a significant 29% reduction in connector temperatures (up to 12.28°C), promoting optimal performance and stability for even the most demanding graphics cards.

Compatibility & Connectivity
Etched Cables
Made from a pliable premium material, these etched cables are easily flexible during installation, and they operate at temperatures 50°C lower than the safety limit when routed for cable management. These cables also meet the rigorous standards of the UL1581 flame test and UL758 certification, helping to ensure a smooth PC DIY experience and exceptional safety.
