Toughpower GF A3 Gold 850W Fully Modular 80+ Gold ATX 3.1 Power Supply
Quiet Confidence, Industrial Strength. From the minds at Thermaltake – a name synonymous with refined thermal performance – the Toughpower GF A3 steps in with whisper-quiet precision and enduring strength. Designed around the latest Intel ATX 3.1 and PCIe Gen 5.1 standards, it delivers clean, stable current with the reliability you’d expect from industrial-grade power architecture. Toughpower GF A3 series is 80 PLUS Gold certified and is compatible with Intel’s ATX 3.0 specifications. Designed with a native PCIe Gen 5.0 connector, it can power up next-gen technology with one new 12VHPWR cable. The GF A3 Gold series delivers 80 PLUS Gold efficiency, it also offers stability, durability, and reliability.
Please note: The wattage marked on the 12VHPWR’s connector is the recommended wattage. (Ref. Intel design guideline).
The native 16 PIN (12VHPWR) PCIe connector of the GF A3 850W can deliver up to 450W for PCIe 5.0 graphics cards.
Complies with the Latest Graphics Cards
Made for heavy lifting The GR A3 is built for high-demand, high-throughput hardware with a native 12VHPWR (12+4-pin) connector, the GF A3 delivers direct, uninterrupted current to today’s most power-hungry graphics cards. A high-amperage single +12V rail ensures consistent voltage delivery across the board, making it a natural fit for performance builds, workstations, and overclocked rigs alike. Powerful single +12V rail can properly deliver the power you need for the best compatibility. The use of LLC and DC to DC circuit design provides very stable operation and enhanced voltage regulation.
Silent, Smart and Always Cool
Smart Zero Fan Featuring a 120mm fluid bearing fan to deliver excellent airflow. Furthermore, the Smart Zero Fan will not spin until the load exceeds 40% of the power supply, minimizing undesired noise.
PCIe Gen 5.0 Ready
