Power Supply Thermaltake Toughpower GF A3 1050W ATX 3.1 80 Plus Gold PSU - PS-TPD-1050FNFAGE-H

Thermaltake Toughpower GF A3 1050W is a high-class modular ATX power supply aimed at serious gaming and workstation configurations with powerful GPUs and plenty of peripherals. With 1050W and an 80+ Gold certification, you have a stable and efficient foundation for a modern high-end build. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 means you are covered for the new generation of graphics cards with a 12VHPWR connector. Despite the power, the case is a standard ATX format with a length of 140 mm, making it easier to fit in most cases.

What you get

With a nominal efficiency of around 90% at typical load, this power supply loses less energy as heat and puts less strain on the electrical installation, especially when combined with a powerful CPU and high-end GPU. A 12+4 pin PCI-E (PCI-E Gen5 12VHPWR) connector allows you to directly power modern graphics cards without the need for adapters, while another 5 x 6+2 Pin PCI-E provides options for classic GPUs or additional cards. 12 x SATA connectors are sufficient for a serious array of SSDs and HDDs, NAS-like builds, or plenty of storage for projects, media, and games. The modular design allows you to use only the necessary cables, improving airflow and simplifying cable management. Active PFC and a wide input range of 100 – 240 VAC ensure stable operation even in more unstable networks.

• Power 1050W – sufficient for high-end configurations with powerful GPUs, plenty of storage, and future upgrades without fear of power shortages.
• 80+ Gold efficiency (around 90%) – lower consumption from the outlet and less emitted heat during long gaming or rendering sessions.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – readiness for the latest generation of graphics cards and better performance during sudden peak loads.
• 1 x 12+4 Pin PCI-E (12VHPWR) + 5 x 6+2 Pin PCI-E – flexibility for new and old GPUs, multi-GPU, or additional expansion cards.
• 12 x SATA, 4 x Molex and 1 x Floppy adapter – covers large RAID arrays, fan controllers, and older hardware that still works for you.
• Modular design – cleaner interior appearance, better airflow, and easier installation since you only plug in what you need.
• Compact ATX size 140 x 150 x 86 mm – easier fit in shorter cases without sacrificing power.
• 120 mm fan – provides cooling for internal components under heavy load.
• 120 months warranty – 10 years coverage, which is a strong indicator of trust in long-term reliability.

Who it is suitable for

This power supply is a logical choice if you plan or already have a next-generation high-end GPU, many drives, and want a configuration that lasts for years without worrying about replacing the PSU. It is also suitable for creators with heavy renders, 3D projects, or streaming setups with plenty of peripherals. If you are building a budget or mid-range build, this power is rather excessive, and you can go down a class or two.

The most sensible aspect here is the combination of 1050W, ATX 3.1 with 12VHPWR, and the long 10-year warranty – you get a modern, powerful, and reliable power supply that can withstand several generations of upgrades.
