Thermaltake Toughpower GF1 850W (2019)

Launched in 2019 as part of Thermaltake’s Toughpower GF1 Gold family, the Toughpower GF1 850W is a fully modular ATX PSU rated 80 PLUS Gold. It features a 140 mm hydraulic‑bearing fan with Smart Zero Fan, Japanese 105°C capacitors, and a 10‑year warranty. Positioned as a high_end Gold unit, it exists to power single‑GPU enthusiast PCs quietly without moving to pricier Platinum/Titanium tiers. Its 850 W capacity and six 6+2‑pin PCIe connectors suit high‑end GPU builds and mid‑range gaming rigs with overclocking headroom, while modular cabling simplifies clean routing in standard ATX cases. Notable: the fan stops at low load for silent operation.
