Thermaltake Toughpower GF A3 1050W TT Premium Edition power supply

1050W ATX 3.0 power supply for modern PCs

This fully modular unit delivers 1050W total output and meets Intel ATX 3.0 specifications. It includes a native 16-pin 12VHPWR connector for PCIe 5.0 graphics cards. The design targets builders who want a single-cable GPU connection and 80 PLUS Gold efficiency. Builders needing more than 1050W should choose a higher-wattage model.

Native 12VHPWR connector with 300W delivery

The single specification that decides fit is the 12VHPWR connector rated for up to 300W on the PCIe 5.0 cable. This allows direct power to compatible graphics cards without adapters. If your GPU uses only traditional 8-pin connectors, this specific feature goes unused. Buyers with older cards that lack a 12VHPWR socket will not benefit from the native cable.

1050W capacity handles high-end single-GPU systems

At 1050W the unit comfortably powers a flagship GPU and a high-performance CPU together with headroom for transient spikes up to 200 percent excursion. The 80 PLUS Gold rating ensures efficient operation at typical loads. Systems planning dual flagship GPUs or extreme overclocking beyond 1050W will exceed this unit's continuous rating.
