be quiet! Straight Power12 1200W ATX 3.1 80 PLUS Platinum Power Supply

This 1200W power supply is built to ATX 3.1 specification, providing native support for two 12VHPWR connectors for PCIe 5.0 graphics cards alongside four PCIe 6+2-pin connectors for current-generation GPUs. The single 12V rail delivers continuous power and can handle transient spikes up to double the rated output, which suits demanding systems with high-end components. An 80 PLUS Platinum rating ensures efficient conversion of mains power to system power.

The unit employs a Silent Wings fan with optimised blade design and fluid-dynamic bearing to minimise noise during operation. Internal cooling benefits from a funnel-shaped inlet and wire-free layout that directs air across all components. Construction uses only Japanese 105°C capacitors for stability and longevity. Fully modular sleeved cables up to 100cm in length aid installation and cable management.
