Know before you buy
Yes, the Toughpower GF3 is fully ATX 3.0 and PCIe 5.0 compliant. It includes a native 12+4pin connector, allowing you to power the latest high-end GPUs directly without needing bulky adapters.
Being fully modular means all cables can be detached from the power supply unit. This allows you to use only the cables you actually need, which significantly reduces clutter and improves airflow inside your PC case.
Not at all. It features a Smart Zero Fan mode that keeps the 13.5cm fan stationary when the power supply is under low loads, ensuring silent operation during basic tasks like web browsing or document editing.
Yes, it is equipped with a full suite of industrial-grade protections, including Over Voltage, Under Voltage, Over Power, Short Circuit, Over Current, and Over Temperature protection to keep your hardware safe.
The unit measures 160mm in depth, which is standard for most ATX cases. However, we recommend checking your specific case's power supply clearance to ensure there is enough room for the unit and the cable connections.
This unit is 80 PLUS Gold certified, meaning it is highly efficient at converting AC power to DC power. This results in less wasted energy as heat and lower electricity consumption during operation.
