Thermaltake Toughpower GF1 850W Power Supply PS-TPD-0850FNFAGU-1

850W ATX power supply for high-end builds

The Thermaltake Toughpower GF1 850W is a fully modular ATX12V unit rated at 850 W and certified 80 PLUS Gold. It targets enthusiasts who need stable, efficient power for multi-GPU configurations and high ambient temperatures up to 50°C. A single +12 V rail and ripple below 30 mV keep performance-critical components running reliably. Japanese capacitors rated at 105°C back the 10-year warranty.

Full modularity and zero-cable platform

Every cable detaches so only the required connectors remain in the case, reducing clutter and improving airflow. The Zero-Cable Platform solders daughterboards directly to the main PCB via a copper plate, enhancing heat dissipation and output quality. Six 6+2-pin PCIe connectors and twelve SATA power connectors support SLI and CrossFire multi-GPU setups. A 140 mm hydraulic-bearing fan spins only after 30 % load, and a rear switch forces constant rotation if preferred.

Upgrade from lower-wattage or group-regulated units

Builders moving from 650 W or non-modular designs gain the headroom for dual high-end graphics cards and the cleaner cable routing of full modularity. The Gold-rated efficiency reaches 90 % at typical loads, cutting waste heat versus Bronze units. Intel C6/C7 state readiness ensures compatibility with modern low-power idle modes. The 160 mm depth fits standard ATX cases, while 16 AWG CPU and PCIe cables handle higher current without voltage drop.
