THERMALTAKE Toughpower GF A3 1050W 80+ Gold Fully Modular ATX 3.1 Power Supply ( 1050W )

The Thermaltake Toughpower GF A3 1050W is a fully modular power supply built to the ATX 3.1 specification, making it a capable foundation for high-end desktop builds that rely on the latest PCIe 5.0 and 5.1 graphics cards. It carries an 80 PLUS Gold certification, meeting efficiency targets at 115 V AC input, and supports Intel Lake C6/C7 processor power states for optimised energy saving across the full system. At the heart of its GPU connectivity is a native 16-pin (12VHPWR) PCIe Gen 5.1 connector rated to deliver up to 600 W to compatible graphics cards, eliminating the need for adapters on next-generation hardware. Five additional PCIe 6+2-pin connectors broaden compatibility for multi-GPU or high-powered single-card configurations. Storage connectivity is equally generous, with 12 SATA connectors and 4 peripheral 4-pin connectors included. Thermaltake has engineered the GF A3 to handle the demanding transient power loads characteristic of modern GPUs. ATX 3.1 compliance includes support for up to 200% power excursion headroom and meets required power-supply timing standards, so the unit can absorb sudden spikes without tripping protection circuits. A high-amperage single +12V rail, LLC resonant conversion, and DC-to-DC topology work together to deliver tightly regulated, stable output across all loads. The cooling solution pairs a 120 mm fluid dynamic bearing (FDB) fan with Thermaltake's Smart Zero Fan mode: the fan remains completely stationary until system load exceeds 30% of rated capacity, keeping acoustics at a minimum during light or idle workloads. When the fan does spin, the FDB design ensures smooth, long-lasting operation. Internal components include a high-quality Japanese main electrolytic capacitor, contributing to longevity and stable rail voltages. Six hardware-level protections are built in: 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).
