Power Supply Unit Thermaltake Toughpower PF1 850 W

The Thermaltake Toughpower PF1 850 W is a fully modular power supply unit designed for high-performance desktop PCs. It delivers up to 850 W of continuous power with 80 PLUS Platinum efficiency and a compact enclosure (140 mm depth) that eases cable management. The unit uses a 120 mm hydraulic bearing fan with Smart Zero Fan control and employs new single-side SMD PCB technology together with premium Japanese 105°C capacitors to ensure stable voltage, low noise and long-term reliability.

Advantages

The PF1 provides high energy efficiency (up to 90%) certified to 80 PLUS Platinum, strict voltage regulation within ±2% on major rails, and ripple noise below 30 mV across +12 V, +5 V and +3.3 V under all loads. Its fully modular low-profile flat cables reduce clutter and improve airflow, while the compact dimensions and single-sided SMD board allow effective cooling by the 120 mm fan. Premium Japanese capacitors and a high-amperage single +12 V rail contribute to stable, durable power delivery.

Key specifications

How to use

Install the PSU in a compatible ATX or mid-tower case aligning the mounting holes and secure with screws. Connect the 24-pin ATX cable to the motherboard and attach the required CPU (EPS) and PCIe connectors to the processor power and graphics cards. Use the modular SATA and Molex cables for drives and peripherals, routing flat cables to optimise airflow. Ensure AC input is within 100–240 V and power on the system. The Smart Zero Fan will remain off under light loads and automatically start above approximately 30% load.

Recommendations

For reliable operation, allow sufficient ventilation around the PSU, keep modular cable connections clean and firmly seated, and avoid operating beyond the rated 850 W continuous power. Match the PSU capacity to system peak loads and use compatible connectors for CPU and GPU power to ensure stable supply.
