Power Supply Unit Thermaltake Toughpower GT 1200W 24-pin ATX Black

The Toughpower GT Series is a fully modular ATX 3.1-compatible power supply offering 80 PLUS Gold efficiency and a native PCIe 12V-2x6 (12+4 pin) modular interface for next-generation graphics cards. Available with up to 1200 W output, it includes a 24-pin ATX motherboard connector and an ultra-quiet 120 mm hydraulic bearing fan with Smart Zero Fan control. The unit uses a high-amperage single +12V rail and LLC plus DC-to-DC circuitry for stable voltage regulation, and features low-profile flat black modular cables for easier cable management. Industrial-grade protections are integrated to safeguard system components, and the series is backed by a multi-year warranty.

Advantages

This PSU delivers high energy efficiency certified to 80 PLUS Gold, reducing wasted power and heat. Native PCIe 12+4-pin support enables direct connection to modern GPUs and can provide up to 600 W through the bundled 12+4 pin cable on the 1000 W model. Full ATX 3.1 compliance ensures compatibility with current timing and excursion requirements. The single +12V rail and advanced circuit design offer reliable and stable power delivery, while fully modular, low-profile cables improve airflow and simplify internal layout. Built-in protections (OCP, OVP, UVP, OPP, SCP, OTP) protect hardware from common electrical faults.

How to use

Install the PSU into a compatible ATX chassis and connect the 24-pin ATX cable to the motherboard. Attach required PCIe power cables to the graphics card using the modular connectors; follow the GPU manufacturer’s connector and wattage recommendations. Ensure the PSU input voltage matches local mains (100–240 V). Allow the Smart Zero Fan to operate automatically: it remains stopped at low loads and spins up as needed to maintain safe operating temperatures. Route modular low-profile cables to optimize airflow and secure connections before powering on the system.

Recommendations

If you plan to use high-power GPUs, verify the required PCIe cable configuration and recommended wattage from the GPU vendor. Use appropriate ventilation in the case to take advantage of the low-profile cables and ensure the PSU is compatible with your chassis dimensions and connector layout.
