Toughpower GF A3 Gold 850W at a Glance
Introduction
The Thermaltake Toughpower GF A3 Gold 850W Power Supply (PS-TPD-0850FNFAGD-H) is designed for gaming PCs, enthusiast builds and compatible high-performance desktop systems that require reliable, efficient power delivery. Its 850W continuous output provides power for demanding processors, graphics cards, storage devices and other system components within the PSU's rated capacity.
The 80 PLUS Gold certification indicates that the power supply meets specified power-conversion efficiency requirements. Its compatibility with Intel ATX 3.0 specifications and native PCIe Gen 5.0 12VHPWR connectivity supports compatible next-generation graphics cards. Thermaltake specifies up to 450W of GPU power through the native 12VHPWR connector on this 850W model.
The fully modular design allows users to connect only the required cables, helping simplify cable management. Its 150 × 86 × 140mm chassis supports installation in compatible ATX cases, subject to PSU clearance and cable-routing space.
Key Features
850W Continuous Power
Provides 850W of rated continuous output, with a single +12V rail rated at 70.8A for compatible processor and graphics-card power requirements.
80 PLUS Gold Efficiency
Gold-certified power conversion helps reduce energy lost as heat under specified operating conditions. Actual efficiency varies with input voltage and system load.
Native PCIe Gen 5.0 Connectivity
Includes one native 12+4-pin 12VHPWR connector rated for up to 450W GPU power on the documented 850W model. Always follow the graphics-card manufacturer's power requirements.
Compact 140mm Chassis
The 140mm PSU depth helps simplify installation in compatible cases while leaving room for cable routing where the cabinet layout permits.
Fully Modular Cables
Connect only the required cables. The low-profile flat black cables help reduce clutter and make cable management easier inside the PC cabinet.
Built-In Protection
The documented GF A3 series includes over-current, over-voltage, under-voltage, over-power, short-circuit and over-temperature protection.
Power Delivery and Cooling Technology
The Toughpower GF A3 Gold 850W uses a single +12V rail rated at 70.8A, with up to 849.6W available on the +12V output in the documented specification. This rail supports the primary power demands of the processor and graphics card within the PSU's overall rated capacity.
Its LLC resonant circuit and DC-to-DC conversion design support stable operation and voltage regulation. The native 12VHPWR connector can deliver up to 450W of GPU power on the documented ATX 3.0 model, subject to graphics-card compatibility and installation requirements.
The 120mm fluid dynamic bearing fan provides cooling airflow, while the fully modular low-profile cables simplify cable routing. Thermaltake also specifies a high-quality Japanese main electrolytic capacitor for the GF A3 series.
ATX 3.0 compatibility supports specified power-excursion requirements. The 80 PLUS Gold rating describes conversion efficiency under defined test conditions; actual efficiency and electricity consumption depend on the connected system and its workload.
