Virtalähde Thermaltake TOUGHPOWER GF A3 650 W

Toughpower GF A3 650 W is an 80 PLUS Gold certified power supply unit compliant with Intel ATX 3.0 specifications. It includes a native 16-pin (12VHPWR) PCIe Gen 5.0 connector that can deliver up to 300 W for PCIe 5.0 graphics cards and is designed to power next-generation hardware while maintaining stable and efficient operation. The unit features a 24-pin ATX motherboard connector, a 120 mm fluid bearing fan, fully modular low-profile flat cables and Japanese main electrolytic capacitors for improved durability.

Advantages

The Thermaltake TOUGHPOWER GF A3 650 W offers high energy efficiency with 80 PLUS Gold certification and Cybenetics Platinum efficiency rating, native PCIe Gen 5.0 16-pin connector for modern GPUs, and full compatibility with Intel ATX 3.0 power excursion and timing standards. It includes built-in industrial-grade protections (OCP, OVP, UVP, OPP, SCP, OTP), a smart zero fan mode that keeps the 120 mm fan off under light loads, and a high-amperage single +12V rail with LLC and DC-to-DC circuitry for stable voltage regulation.

How to use

Install the TOUGHPOWER GF A3 650 W into a compatible PC chassis and connect the 24-pin ATX cable to the motherboard and the required modular cables to the storage devices, fans and GPU. For PCIe Gen 5.0 graphics cards, use the native 16-pin (12VHPWR) connector; follow the wattage guidance printed on the 12VHPWR cable as a recommended limit. Ensure the PSU is connected to a proper mains source within the 100–240 V input range and verify all connectors are fully seated before powering on the system.

Recommendations

Use the native 12VHPWR 16-pin connector for modern PCIe 5.0 graphics cards and observe the recommended wattage printed on the cable. Keep the PSU ventilation unobstructed and use modular cables as needed to improve airflow and cable management inside the chassis.
