THERMALTAKE Toughpower GF A3 750W 80+ Gold Fully Modular ATX 3.1 Power Supply ( 750W )

The Thermaltake Toughpower GF A3 750W is a fully modular ATX 3.1 power supply built for builders who want to future-proof their systems against the demands of next-generation graphics cards and platform standards. Certified to 80 PLUS Gold, it delivers up to 90% efficiency at 115 V input, helping reduce energy waste and heat inside your chassis. Compliance with Intel ATX 3.1 specifications means the unit supports up to 200% power excursion headroom, meets 60% low-load efficiency requirements, and adheres to required power-supply timing standards — giving modern GPU transient loads the headroom they need. At the heart of the connector lineup is a native PCIe Gen 5.1 16-pin (12V-2x6) connector rated to deliver up to 300 W, letting current-generation discrete GPUs connect with a single, clean cable rather than multiple adapters. Four additional PCIe 6+2-pin connectors are included for legacy GPU configurations, and eight SATA plus four 4-pin peripheral connectors cover storage-dense and multi-device builds. Cooling is handled by a 120 mm fluid dynamic bearing (FDB) fan. The Smart Zero Fan mode keeps the fan stationary until the load exceeds 40% of rated output, so the system runs silently during light workloads. Japanese main electrolytic capacitors are used on the primary side, supporting a rated MTBF of 100,000 hours minimum and reinforcing long-term reliability. Circuit topology combines LLC resonant conversion with a DC-to-DC secondary stage for tight voltage regulation across all rails. A single high-amperage +12 V rail feeds the entire load. Built-in protection circuits cover OCP (over-current), OVP (over-voltage), UVP (under-voltage), OPP (over-power), SCP (short-circuit), and OTP (over-temperature). The fully modular cable design uses low-profile flat black cables, simplifying cable routing, reducing chassis clutter, and improving airflow. Thermaltake backs this unit with a 10-year warranty.
