Flawless Cooling Concept

The funnel-shaped fan inlet of the Straight Power 12 850W increases airflow while reducing unwanted turbulence for higher cooling performance. The wire-free design inside allows the cool air to reach all components which ultimately leads to a longer lifespan.

Future-Proof Your System

Straight Power 12 850W is an ATX 3.0 PSU and comes with both native integration of the 12VHPWR connector for next-generation PCIe 5.0 graphics cards, and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come.

Modular Cables

Modular, sleeved cables of up to 100cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling – even in the largest PC cases.
