850W ATX 3.0 Power Supply

The Thermaltake Toughpower GF A3 850W Gold TT Premium Edition is a fully modular ATX 3.0 compatible power supply. It delivers 850W of continuous power with 80 PLUS Gold certified efficiency. The unit includes a native 16-pin 12VHPWR connector ready for PCIe Gen 5.0 graphics cards. Japanese main electrolytic capacitors support long-term reliability.

Suited for modern PC builds needing ATX 3.0 support

This unit suits builders assembling systems with current-generation GPUs that require a native 12VHPWR connection. The 850W output handles high-performance single-GPU configurations comfortably. Builders planning multi-GPU setups or extreme overclocking headroom should look at higher wattage units. Cases with severe length restrictions under 150mm cannot accommodate this PSU.

Native 12VHPWR connector for PCIe Gen 5.0

The defining specification is the native 16-pin 12VHPWR cable designed for PCIe Gen 5.0 graphics cards. This connector can deliver up to 300W directly to a compatible GPU without adapters. ATX 3.0 compliance ensures support for 200% power excursions and 60% low-load efficiency requirements. This connector determines whether the PSU matches your graphics card's power input.

Soalan tentang produk ini

Will the 12VHPWR connector run a PCIe 5.0 graphics card without an adapter?

Yes, the native 16-pin 12VHPWR cable is included and rated for up to 300 W on PCIe 5.0 cards.

Does the 150 mm depth leave clearance in a standard mid-tower case?

At 150 mm deep the unit fits most mid-tower chassis; measure your case’s PSU bay to confirm.

Is the PSU fully modular so I only connect the cables my build needs?

Fully modular design lets you attach only the required cables, reducing clutter and improving airflow.
