Thermaltake Toughpower PF3 1050W 80 PLUS Platinum Power Supply

The Thermaltake Toughpower PF3 1050W is a fully modular ATX 3.0 power supply unit designed for high-performance desktop builds that demand both efficiency and future-ready connectivity. Certified to the 80 PLUS Platinum standard, it converts mains power with high efficiency across a broad load range, minimising wasted energy and internal heat generation compared to lower-tier certifications. Built to Intel ATX 3.0 specifications, the PF3 1050W supports up to 200% power excursion, reaches 70% efficiency at low load, and meets required power supply timing standards — making it compatible with the power delivery demands of modern platforms. A native 16-pin (12VHPWR) PCIe Gen 5 connector is included, enabling direct, single-cable connection to the latest discrete graphics cards at up to 600W, eliminating the need for adapter cables. The unit features a single high-amperage +12V rail with an LLC resonant converter and DC-to-DC circuit design for stable, tightly regulated voltages across all outputs. Internal components include 100% Japanese 105°C-rated electrolytic capacitors throughout, a specification that supports longevity under sustained thermal stress. A 120mm fluid dynamic bearing fan provides cooling while maintaining low acoustic output. The Smart Zero Fan function reduces fan speed at light loads to minimise noise during everyday computing tasks. The compact 140mm-deep chassis fits a wide range of mid-tower and full-tower enclosures without compromising cable management space.
