Toughpower GF A3 Gold 1050W at a Glance
Introduction
The Thermaltake Toughpower GF A3 Gold 1050W Power Supply (SKU supplied: PS-TPD-1050FNFAGD-H) is designed for demanding gaming PCs, enthusiast builds and compatible high-performance workstations. Its 1050W continuous output provides substantial power capacity for modern processors, high-end graphics cards, storage devices and other components within the PSU's rated limits.
The 80 PLUS Gold certification indicates that the PSU meets defined power-conversion efficiency requirements. Its ATX 3.0 compatibility and native PCIe Gen 5.0 12VHPWR connector support compatible next-generation graphics cards. Thermaltake specifies up to 600W of GPU power through the native connector on the documented GF A3 Gold 1050W model.
The fully modular design allows users to connect only the required cables, helping simplify cable management and improve airflow around installed components. Its 150 × 86 × 140mm chassis supports installation in compatible ATX cases, subject to available PSU clearance and cable-routing space.
Key Features
1050W Continuous Power
Provides 1050W of rated continuous output, with a single +12V rail rated at 87.5A 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 600W GPU power on the documented GF A3 Gold 1050W model. Follow the graphics-card manufacturer's power and installation 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 Low-Profile Cables
Connect only the required cables. The low-profile flat black cables help simplify cable routing, reduce clutter and improve airflow inside the PC cabinet.
Comprehensive 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 1050W uses a single +12V rail rated at 87.5A, providing up to 1050W on the +12V output in the official 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 is rated for up to 600W of GPU power on the documented 1050W model, subject to graphics-card compatibility and installation requirements.
The 120mm fluid bearing fan provides cooling airflow. Smart Zero Fan technology keeps the fan stopped until the PSU load exceeds approximately 30%, helping reduce fan noise during lighter workloads. A high-quality Japanese main electrolytic capacitor is also specified for the GF A3 Gold series.
ATX 3.0 compatibility supports the specified power-excursion requirements. The 80 PLUS Gold rating describes power-conversion efficiency under defined test conditions; actual efficiency and electricity consumption depend on the connected system and its workload.

Custom ATX Builds
Fully modular cabling and a 140mm chassis depth help with installation and cable management in compatible ATX cases.
Before You Build
- Check the recommended PSU wattage for your exact processor and graphics card before buying.
- Verify the supplied product label against the exact SKU. Thermaltake's official black GF A3 Gold 1050W reference uses part number PS-TPD-1050FNFAGA-H.
- The fully modular PSU includes five PCIe 6+2-pin connectors and one native 12VHPWR connector rated for up to 600W on the documented model.
- Follow the graphics-card manufacturer's instructions for 12VHPWR connections. Ensure the connector is fully inserted and avoid sharp bends close to the connector.
- Use only genuine Thermaltake cables supplied with the PSU or replacements explicitly approved for the exact model. Modular cables are not universally interchangeable.
- Confirm cabinet clearance, included cables and applicable regional warranty terms before purchase.
