THERMALTAKE Toughpower GF A3 Gold 1050W 80 Plus 3.0 Gold Fully Modular Power Supply

The Thermaltake Toughpower GF A3 Gold 1050W is a fully modular power supply built to meet Intel ATX 3.0 specifications. It carries an 80 PLUS Gold efficiency certification, delivering strong efficiency at typical load levels when operating at 115 V AC input. The unit is designed for builders who need reliable, high-wattage power delivery for current and next-generation PC hardware. At the heart of its next-gen readiness is a native 16-pin PCIe Gen 5.0 12VHPWR connector capable of delivering up to 600 W to compatible PCIe 5.0 graphics cards. In addition, five PCIe 6+2-pin connectors provide flexibility for multi-GPU or high-end single-GPU configurations. ATX 3.0 compliance means the unit supports up to 200% power excursion handling, critical for GPU transient spikes, and reaches the required 60% low-load efficiency threshold. The cooling system uses a 120 mm fluid dynamic bearing (FDB) fan that operates silently under light loads. Thermaltake's Smart Zero fan mode keeps the fan stationary until system load exceeds 30%, significantly reducing noise during everyday desktop use or light gaming sessions. Power delivery is managed through a single high-amperage +12V rail, underpinned by LLC resonant conversion and DC-to-DC circuitry for stable voltage regulation across all rails. The fully modular cable design uses low-profile flat black cables, making cable routing and airflow management straightforward inside the chassis. Built-in industrial-grade protections include Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP). The unit accepts universal input voltage ranging from 100 V to 240 V AC at 50–60 Hz, making it suitable for use in multiple regions.
