be quiet! Straight Power 12 750W ATX 3.1 Power Supply

The be quiet! Straight Power 12 750W delivers exceptional efficiency and near-silent operation for high-performance PC builds. This ATX 3.1 power supply achieves 80 PLUS Platinum certification with up to 93.8% efficiency at 50% load, reducing power consumption and heat generation.

ATX 3.1 Standard with PCIe 5.1 Support

Built to support next-generation graphics cards, this PSU includes a native 12V-2x6 connector for PCIe 5.1 GPUs alongside four PCIe 6+2-pin connectors for current-generation cards. The single 12V rail delivers 750W continuous power and handles power excursions up to double its rated capacity, ensuring stable operation during demanding workloads and GPU transient spikes.

Silent Wings 135mm Fan Technology

The integrated Silent Wings 135mm fan operates virtually inaudibly while maintaining optimal cooling. The funnel-shaped fan opening on the PSU case maximizes airflow intake, allowing the fan to run at lower speeds even under load. This design keeps your system quiet during gaming sessions and intensive tasks.

Premium Components and Full Bridge LLC

Japanese 105°C capacitors provide superior stability and longevity, backed by a 10-year manufacturer warranty. Full bridge LLC technology ensures unmatched signal stability across all voltage rails, protecting your components from power fluctuations. The +3.3V and +5V rails deliver 25A each with a combined 130W output, while the 12V rail provides 62.5A.

Fully Modular Cable Management

Nine sleeved modular cables allow you to connect only what your system requires, improving airflow and aesthetics. The package includes one 20+4-pin ATX motherboard cable (60cm), one P4+4 CPU cable, one P8 CPU cable, one 12V-2x6 cable, four PCIe 6+2-pin cables, nine SATA connectors, and two PATA connectors. Maximum cable length reaches 100cm for flexible routing in larger cases.
