ATX 3.1 1000W Fully Modular PSU

The Thermaltake Toughpower GT 1000W is a fully modular ATX power supply built for builders who need a clean, high-wattage unit with modern connector support. It carries 80 PLUS Gold certification and meets ATX 3.1 specifications for power excursion and timing. The single 12V-2x6 cable can deliver up to 600 W to a compatible graphics card. Value-focused users get native PCIe 5.1 readiness without paying for flagship features.

ATX 3.1 power excursion and connector limits

ATX 3.1 allows the supply to handle transient loads up to 200 % of its rated output for short periods. The 12V-2x6 interface is rated for 600 W on the included cable, so cards drawing more than that will need a different power solution. Efficiency must reach 60 % at low load under the standard, but the unit does not guarantee a specific fan-off threshold. The 120 mm hydraulic-bearing fan runs under Smart Zero Fan control to reduce noise at light loads.

Compatibility checks before ordering

Verify that your case can fit a standard ATX power supply and that your motherboard has the required 24-pin and CPU power headers. Ensure the graphics card you plan to use has a 12V-2x6 or 12+4-pin connector rated for 600 W or less. Confirm the total system draw stays within the 1000 W continuous rating, because the 200 % excursion figure covers only brief spikes. Input voltage auto-ranges from 100 to 240 V for worldwide use.

The product listed here is the 1000 W model. Other wattages may exist in the range but are not covered by this page.

What does the 1000 W rating mean for a system with a modern graphics card?

The 1000 W maximum power can sustain high-end components, and the native 12V-2x6 cable is rated to deliver up to 600 W to a PCIe 5.1 graphics card.

How does the ATX 3.1 standard affect what this unit can actually supply?

ATX 3.1 compliance means the PSU supports up to 200 % power excursion and meets the required timing standards for current platforms.
