Napájací zdroj Thermaltake TOUGHPOWER GF A3 750 W

The Thermaltake TOUGHPOWER GF A3 750 W is an ATX 3.0 compatible power supply unit offering 750 W output and 80 PLUS Gold efficiency. It features a native 16-pin (12VHPWR) PCIe Gen 5.0 connector for next-generation graphics cards, a 24-pin ATX motherboard connector, and an active 120 mm cooling fan with Smart Zero Fan operation. The unit supports an AC input of 100–240 V at 50/60 Hz and uses high-quality Japanese main electrolytic capacitors and LLC plus DC-to-DC design for stable voltage regulation.

Advantages

The TOUGHPOWER GF A3 750 W provides PCIe Gen 5.0 readiness via a native 16-pin 12VHPWR connector capable of delivering up to 300 W to compatible GPUs, and it complies with Intel ATX 3.0 specifications including power excursion and timing requirements. It delivers high efficiency (80 PLUS Gold) and is Cybenetics Platinum (efficiency) and A- (noise) certified for the 650 W model parameters. The PSU includes full industrial-grade protections (OCP, OVP, UVP, OPP, SCP, OTP), a high-amperage single +12V rail, fully modular low-profile flat black cables for improved cable management, and a fluid-bearing 120 mm fan with Smart Zero Fan control to reduce noise at low loads.

Suitable for

• Gaming PCs with next-generation PCIe 5.0 graphics cards
• Workstations requiring stable +12V power delivery
• Systems where compact cable management and airflow are important

Key specifications

• Total power: 750 W

How to use

Install the PSU into a compatible ATX chassis and connect the 24-pin ATX connector to the motherboard. Use the included modular flat cables to connect SATA, peripheral, and PCIe power connectors as required by your components. If using a PCIe 5.0 graphics card, connect the native 16-pin (12VHPWR) cable directly to the GPU; follow the wattage marking on the 12VHPWR connector as the recommended limit per Intel guidelines. Ensure proper airflow around the 120 mm fan and secure all connections before powering on the system.

Recommendations

To ensure longevity and optimal performance, operate the PSU within its rated load and ambient temperature ranges, verify cable compatibility with your GPU model, and allow the Smart Zero Fan to remain inactive at low loads to reduce noise. Follow manufacturer instructions for handling and installation.
