Thermaltake TOUGHPOWER GT 1000W ATX 3.1

The Thermaltake TOUGHPOWER GT 1000W (PS-TPT-1000FNFAGK-3) is built to power the most demanding PC builds — from high-end gaming machines to professional content creation systems. With a full 1000 W output, this PSU delivers robust and consistent power to high-TDP CPUs and modern graphics cards.

Thanks to its 80 PLUS Gold rating, the TOUGHPOWER GT runs efficiently, reducing wasted energy and heat generation. It’s designed around the ATX 3.1 standard, which supports large transient power spikes — making this unit very future-proof.

One of the standout features is the built-in PCI-e Gen 5.1 (12V-2×6) connector, enabling direct support for next-gen GPUs without the need for adapters. This native connector can deliver up to 600 W, ensuring stable and efficient power delivery under heavy GPU loads.

Thermaltake has also prioritized quiet operation and cooling: the 120 mm hydraulic bearing fan remains off at low loads (thanks to Smart Zero Fan Mode), then ramps up smoothly and silently when the system demands it. The internal design uses a single high-amperage +12V rail combined with a refined LLC and DC-to-DC circuit topology, for tight voltage regulation and stability.

On the safety front, the power supply features a suite of protections — including over-current (OCP), over-voltage (OVP), under-voltage (UVP), over-power (OPP), short-circuit (SCP), and over-temperature (OTP) — safeguarding your components during any fault conditions.

The fully modular design means you only plug in the cables you need, and with low-profile flat black cables, cable management becomes clean and airflow inside your PC case improves. And because it’s built for reliability, the TOUGHPOWER GT 1000W offers an MTBF of 100,000 hours
