Power Supply Unit Thermaltake Toughpower Gt 850 W

Toughpower GT Series is a fully modular power supply designed for desktop systems, delivering 80 PLUS Gold efficiency and compatibility with ATX 3.1 standards. It includes a native PCIe 12V-2x6 (12+4 pin) modular connector to power next-generation graphics cards and is backed by a 5-year warranty, offering reliable performance for users seeking a modern PSU solution.

Advantages

The Toughpower GT provides ATX 3.1 readiness with support for power excursion handling and required timing standards, a PCIe Gen 5.1–ready native 12V-2x6 connector for stable GPU power delivery, an ultra-quiet 120 mm hydraulic bearing fan with Smart Zero Fan control to reduce noise, and a high-amperage single +12V rail with LLC and DC-to-DC circuitry for stable voltage regulation. Fully modular low-profile cables simplify cable management and improve airflow, while built-in industrial-grade protections guard connected components. The unit is 80 PLUS Gold certified, achieving high efficiency up to around 90% under typical loads.

How to use

Install the Toughpower GT in a compatible ATX 3.1 case and connect the fully modular cables to the mainboard, CPU, storage devices and PCIe devices as required. Use the native PCIe 12V-2x6 (12+4 pin) connector for GPUs that require PCIe 12+4 pin power; verify the GPU manufacturer’s recommended power requirements before use. Ensure proper cable routing to maintain clear airflow and connect all required power connectors firmly before powering on the system.

Recommendations

Before connecting the PCIe 12+4-pin cable, compare the recommended wattage printed on the connector against the GPU manufacturer’s specifications. Actual system power demand depends on components and usage, so select a PSU wattage that accommodates peak loads and allow margin for future upgrades.
