Thermaltake Toughpower GF A3 1050 Watt Gold ATX 3.1 Fully Modular SMPS

The Thermaltake Toughpower GF A3 1050W Gold ATX 3.1 is a fully modular power supply built for high-performance desktop systems, including those running the latest PCIe 5.0 and 5.1 graphics cards. Carrying the 80 PLUS Gold certification, it delivers up to 90% energy efficiency at 115 V AC input, keeping your system cool and your electricity bill in check. Compliant with Intel ATX 3.1 specifications, the GF A3 1050W supports up to 200% transient power excursion, 60% low-load efficiency, and mandatory power supply timing standards — ensuring stable operation under the sudden power spikes that modern GPUs can demand. Its native 16-pin (12VHPWR) PCIe Gen 5.1 connector can deliver up to 600 W directly to a single graphics card, eliminating the need for adapter cables and reducing potential failure points. Thermal management is handled by a 120 mm fluid dynamic bearing (FDB) fan paired with a Smart Zero Fan mode: the fan remains completely stationary until system load exceeds 30% of rated capacity, resulting in near-silent operation during light tasks. Once load climbs, the fan spins up smoothly to maintain safe operating temperatures across the 0 °C to +45 °C rated range. Power delivery is built around a high-amperage single +12V rail supported by LLC resonant conversion and DC-to-DC circuitry, providing tightly regulated voltages to every component. The primary filtering stage uses a Japanese main electrolytic capacitor selected for longevity and stability. Protection circuitry covers OCP (Over Current), OVP (Over Voltage), UVP (Under Voltage), OPP (Over Power), SCP (Short Circuit), and OTP (Over Temperature), giving your components multi-layer safeguarding. Safety approvals include CE, FCC, UKCA, ICES, LVD, TUV, cTUVus, CB, CCC, and BSMI.
