850W ATX 3.0 Power Supply

The Thermaltake Toughpower GF A3 Snow Edition delivers 850W of continuous power with 80 PLUS Gold certification. A fully modular design uses low-profile flat black cables for clean routing. The unit meets ATX 3.0 specifications and includes a native PCIe 12+4pin connector rated for 450W.

Built for Modern GPU Builds

This unit suits builders installing current-generation graphics cards that require the 12VHPWR connection. The single +12V rail design and four 6+2-pin PCIe connectors support multi-GPU configurations. Systems needing higher wattage or a different form factor should consider other models.

150mm Chassis Depth

The power supply measures 150mm in length, a critical dimension for case compatibility. Verify that your chassis accommodates this depth before purchase. The compact size fits most mid-tower and full-tower cases designed for standard ATX units.

Questions about this item

How do I connect the 12VHPWR cable and which orientation error should I avoid?

Plug the native 12+4pin modular cable into the PSU port marked PCIe 12VHPWR 450W and seat it fully until the latch clicks; the notch only fits one way so forcing it backwards bends pins.

What component will likely need attention first and what is its rated life?

The 120mm fluid dynamic bearing fan carries a minimum 100,000 hour MTBF; dust buildup on its blades is the first maintenance item, so clean it with compressed air when noise rises.

Which protection trips first during a long full-load session?

Over-temperature protection (OTP) monitors internal heat and will shut the unit down before sustained load pushes components past safe limits.
