1200 W ATX 3.1 power supply

The Thermaltake Toughpower GT 1200W is a fully modular ATX 3.1 power supply rated for 1200 W. It carries 80 PLUS Gold certification and operates on 100 - 240 V input. The unit uses Japanese main capacitors and a 120 mm hydraulic bearing fan with Smart Zero Fan control. It targets builders who need native PCIe 5.1 12V-2x6 connections for current graphics cards.

Native dual PCIe 5.1 12V-2x6 cables

Two native PCIe 5.1 12V-2x6 connectors are included, each able to deliver up to 600 W to a 12+4 pin graphics card. The flat, colour-matched modular cables reduce clutter and simplify routing. ATX 3.1 compliance brings support for 200% power excursion and 60% efficiency at low load. These features matter for systems running high-wattage GPUs that draw transient spikes.

ATX 3.1 case clearance and cable count

Verify that your case accepts a standard ATX power supply with a 120 mm fan and that the modular panel has room for the required cables. Confirm your motherboard uses a 24-pin ATX and the necessary EPS connectors, which are not detailed here. Ensure the 100 - 240 V input range matches your mains supply. Buyers who need more than two 12V-2x6 connectors or a different form factor should look elsewhere.

Questions about this item

Will the 140 mm hydraulic-bearing fan need replacing during the unit's rated life?

The fan uses a hydraulic bearing rated for continuous operation and the unit carries a mean-time-between-failures figure above 100000 hours, so replacement is unlikely within normal service.

What protection kicks in first if the 1200 W output is held continuously?

Over-temperature and over-current circuits monitor the single 12 V rail and will shut the supply down before components exceed safe limits.

How loud and hot does the 120 mm fan get during all-day load?

The Smart Zero Fan keeps the 120 mm hydraulic-bearing fan off at low load and ramps speed only as temperature rises, keeping noise and heat low during extended use.
