Power Supply Unit Thermaltake Toughpower Grand RGB 750W

The Thermaltake Toughpower Grand RGB 750W is a fully modular desktop power supply designed for ATX systems, delivering 750 W of continuous power with peak performance up to 900 W. Built to meet 80 PLUS Gold efficiency, this PSU integrates a preinstalled 14 cm patented 256-color Riing RGB fan with multiple lighting modes, motherboard RGB synchronization, and a 10-year warranty. It uses high-quality Japanese 105°C capacitors, a high-amperage single +12V rail with DC-to-DC design, and low-profile flat cables for easier cable management and improved airflow.

Advantages

The PSU offers up to 90% energy efficiency and Intel C6/C7 states readiness for reduced power consumption. The Riing 14 RGB fan provides five lighting modes, built-in memory and compatibility with ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, ASRock RGB LED and BIOSTAR Vivid LED DJ via a 12V RGB header. Smart Zero Fan operation limits noise under light loads, while concentrated compression fan blades, hydraulic bearings and anti-vibration mounts improve cooling performance and stability. Voltage regulation is kept within ±2% and ripple noise is below 30 mV across major rails. Fully modular low-profile flat cables simplify installation and internal airflow.

Suitable for

• Gaming and high-performance desktop PCs requiring up to 750 W continuous power
• Systems with RGB-configurable motherboards (12V RGB header) for synchronized lighting
• Environments prioritizing quiet operation and efficient energy use
• Builds that benefit from tidy cable management and improved airflow

How to use

Install the PSU into a compatible ATX chassis and connect the 24-pin ATX cable to the motherboard along with required CPU and GPU power connectors from the modular cable set. Use the RGB Sync switch on the rear to select software-controlled or hardware-controlled lighting. For software synchronization, connect the PSU’s RGB ring to a motherboard 12V RGB header and control lighting with supported motherboard software (ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, ASRock RGB LED, or BIOSTAR Vivid LED DJ). Optionally use the RGB button to cycle through the five built-in lighting modes and rely on the memory function to retain the selected color at boot.

Recommendations

Ensure your motherboard has a 12V RGB header for full RGB synchronization. Keep the PSU firmware/software and motherboard RGB software updated from the manufacturer’s support pages. Choose the Smart Zero Fan setting for quieter operation under light loads or switch it off if constant fan cooling is preferred. Verify your system’s total power draw to confirm 750 W is sufficient for your components.
