THERMALTAKE Toughpower GF A3 850W 80+ Gold ATX 3.1 White Fully Modular Power Supply ( 850W )

The Thermaltake Toughpower GF A3 850W (Model: PS-TPD-0850FNFAGD-N) is a fully modular power supply designed for enthusiast and next-generation PC builds. Carrying the 80 PLUS Gold efficiency certification, it meets Intel ATX 3.1 specifications — including support for up to 200% power excursion, 60% low-load efficiency compliance, and required power-supply timing standards — making it a forward-compatible choice for demanding modern platforms. At the heart of its connector lineup is a native 12+4pin (12VHPWR) PCIe Gen 5.1 connector, capable of delivering up to 450W to compatible PCIe 5.0 graphics cards. This single cable replaces multiple legacy adapters and is compatible with NVIDIA RTX 40-series cards that require a PCIe Gen 5.0 connection. Additionally, four 6+2-pin PCIe connectors are included to support AMD graphics cards and entry-level RTX 40-series GPUs, ensuring broad compatibility across GPU ecosystems. The fully modular cable system means only the cables you need attach to the unit, improving internal airflow and simplifying cable management. Cooling is handled by a 120mm fluid bearing fan paired with a Smart Zero Fan mode: the fan remains completely off until system load exceeds 30% of rated capacity, keeping noise levels extremely low during light tasks and idle states. Reliability is reinforced by a high-quality Japanese main electrolytic capacitor, which contributes to long-term stability and durability. A high-amperage single +12V rail — supported by LLC resonant and DC-to-DC circuit topology — delivers stable voltage regulation across varying loads. Comprehensive hardware protection is built in, covering OCP (Over Current), OVP (Over Voltage), UVP (Under Voltage), OPP (Over Power), SCP (Short Circuit), and OTP (Over Temperature) scenarios. The all-white finish makes this unit a natural fit for white-themed builds when paired with components such as the Thermaltake S200 ARGB White cabinet or TH240 V2 ARGB White AIO cooler. Thermaltake backs this power supply with a 10-year warranty.
