What this unit delivers

The Thermaltake Toughpower PT 850W is a fully modular ATX 3.1 power supply rated for 850 W continuous output at 40°C. It carries 80 PLUS Platinum certification at 115Vac input and includes a native PCIe 5.1 12V-2x6 connector capable of 600 W for modern graphics cards. Japanese 105°C electrolytic capacitors and a single +12V rail with DC-DC and LLC topology provide stable delivery under load.

Why upgrade to ATX 3.1 and PCIe 5.1

This unit replaces an older supply that lacks Intel ATX 3.1 compliance or a native 12V-2x6 cable, forcing the use of adapters for current-generation GPUs. The jump is worth it when your graphics card requires up to 600 W through a single connector and you want the efficiency headroom of Platinum certification. The 135mm hydraulic bearing fan and low-profile etched cables also improve airflow and cable routing compared with bulkier, non-modular designs.

What to verify before ordering

Confirm your case can accommodate a 140 mm deep power supply and that the 135mm fan orientation matches your chassis airflow path. Check that the full modular cable set includes the connectors your motherboard, CPU and storage devices need, because only the cables supplied with this unit are guaranteed compatible. Ensure your mains supply falls within the 100-240V~ 47-63 Hz range and that the 12.0 A maximum input current is supported by your circuit.
