Power Supply Unit Thermaltake GF2 650 W

The Thermaltake Toughpower GF2 ARGB 650W Gold is a fully modular 650 W power supply that combines high energy efficiency with customizable addressable RGB lighting. Built with premium Japanese capacitors and a high-amperage single +12V rail, this ATX PSU delivers stable power for modern PC builds. The unit features a patented Riing Duo 140 mm RGB fan with dual rings and 18 addressable LEDs, ARGB side panels for wide illumination coverage, and an active cooling design with a Smart Zero Fan mode to reduce noise at low loads.

Advantages

This Thermaltake power supply is 80 PLUS Gold certified, providing up to around 90% efficiency and compatibility with Intel C6/C7 states for improved energy savings. Voltage regulation is kept within ±2% on the main rails for stable operation, while ripple is maintained below 30 mV across +12V, +5V and +3.3V from 0% to 100% load. Fully modular low-profile flat cables simplify cable management and improve airflow. The unit includes premium 105°C Japanese capacitors and a robust single +12V rail for reliable delivery of power to high-demand components.

Suitable for

• Gaming desktop builds requiring stable 650 W power delivery
• PC systems that benefit from addressable RGB lighting synchronized with motherboard software
• Compact or airflow-optimized cases where flat modular cables improve build tidiness
• Systems that need long-term reliability and tight voltage regulation

How to use

Install the Thermaltake GF2 650W into a compatible ATX chassis using the supplied mounting screws and connect the 24-pin ATX cable to the motherboard. Attach necessary modular cables for CPU, GPU and drives according to your system requirements. For lighting control, connect the PSU's ARGB cable to a 5V addressable RGB header on a compatible motherboard and use the motherboard RGB software (ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync or ASRock Polychrome) to configure colors and effects. The Smart Zero Fan mode keeps the fan stopped until load exceeds 20% to reduce noise in light-load scenarios.

Recommendations

Ensure your motherboard supports a 5V addressable RGB header before relying on software synchronization. Use only the included modular cables or manufacturer-approved replacements. Observe proper airflow in the case and avoid obstructing the ARGB side panels and fan intake to maintain cooling performance and lighting visibility.
