THERMALTAKE TOUGHPOWER GF A3 Gold 850W 80+ Gold ATX 3.0 Fully Modular Power Supply

The Thermaltake Toughpower GF A3 Gold 850W is a fully modular ATX 3.0 power supply designed to handle today’s most demanding desktop builds. Compliant with Intel’s ATX 3.0 specifications, it supports up to 200% power excursion headroom, ensuring stable delivery even during sudden GPU transient spikes — a critical requirement for PCIe Gen 5.0 graphics cards. The unit ships with a native 16-pin (12VHPWR) PCIe connector capable of delivering up to 450W to next-generation GPUs, eliminating the need for daisy-chained adapter cables. Four additional PCIe 6+2-pin connectors are included for multi-GPU or legacy GPU configurations. The fully modular cable design means unused cables stay out of the chassis entirely, improving airflow and simplifying cable management regardless of case size. Cooling is handled by a 12 cm fluid dynamic bearing (FDB) fan, a bearing type chosen for its low noise profile and long service life. Thermaltake rates MTBF at a minimum of 100,000 hours, reflecting the unit’s focus on reliability in continuous-use environments. Efficiency is certified at 80 PLUS Gold at 115 Vac input, and the unit also meets the ATX 3.0 requirement of 60% efficiency at low load — a specification the previous ATX 2.x standard did not mandate. Active PFC ensures a high power factor across the supported input voltage range of 100–240 Vac, making the unit compatible with Indian and international mains supplies. Hold-up time exceeds 17 ms and power-good signal timing spans 100–250 ms, both within ATX compliance margins. Verified Specifications: – Model: TTP-850AH2FKG | P/N: PS-TPD-0850FNFAGD-H – Max.
