Virtalähde Thermaltake Toughpower GF3 750 W

Power Supply Unit Thermaltake Toughpower GF3 750 W is a fully modular 750 W ATX power supply designed for modern desktop PCs and next-generation graphics cards. The unit is 80 PLUS Gold certified and features a native PCIe 12+4pin (16-pin) connector for PCIe Gen 5.0 GPUs, full compatibility with Intel ATX 3.0 / PSDG timing and excursion requirements, a single high-amperage +12V rail, and premium components including 100% Japanese 105°C capacitors.

Advantages

The Toughpower GF3 750W offers high efficiency up to 80 PLUS Gold levels, strict voltage regulation within ±2% on major rails, and low ripple noise below 30 mV across +12V, +5V and +3.3V from 0–100% load. It includes a native 16-pin PCIe Gen 5.0 connector for next-gen GPUs, a Smart Zero Fan mode that keeps the 135 mm FDB fan off under light loads, and a fully modular low-profile flat cable design to simplify cable management and improve airflow.

Suitable for

• Gaming and high-performance desktop builds using PCIe Gen 5.0 graphics cards
• Workstations that require stable single-rail +12V power delivery
• Systems requiring ATX 3.0 / PSDG compliance for power excursion handling
• Compact chassis where low-profile flat cables and good airflow are important

How to use

Install the PSU into a compatible ATX chassis and connect the 24-pin ATX motherboard connector and required CPU/GPU power cables. Use the included modular cables to connect drives and peripherals as needed, preferring the low-profile flat cables to improve routing and airflow. When powering next-generation graphics cards, use the native 16-pin PCIe connector for stable delivery. Ensure the PSU input matches your local AC supply (100–240 V, 50–60 Hz) and secure all connections before powering on the system.

Recommendations

For reliable long-term operation, allow adequate case ventilation, keep the environment dust-free, and avoid continual operation near the maximum rated load. Use the native PCIe 16-pin connector for Gen 5.0 GPUs when available, and replace modular cables with originals from the manufacturer to maintain safety and compliance.
