The be quiet! Pure Power 12 M 750W ATX 3.1 Modular Power Supply (BN504) is engineered to deliver stable, efficient, and ultra-quiet power for modern gaming and performance PCs. Designed to meet the latest ATX 3.1 standard, this 750W PSU provides enhanced reliability and compatibility with next-generation components, including PCIe 5.0 graphics cards.

With 80 Plus® Gold certification, the Pure Power 12 M ensures high energy efficiency of up to 90% or more under typical loads. This means reduced power consumption, lower heat generation, and quieter system operation. Efficient performance not only helps reduce electricity costs but also extends the lifespan of internal components by minimizing thermal stress.

Fully compliant with the ATX 3.1 specification, this power supply is built to handle high transient power spikes from modern GPUs. It includes a dedicated 12VHPWR cable, enabling direct support for PCIe 5.0 graphics cards without requiring adapters. Additionally, it supports GPUs with traditional 6+2 pin PCIe connectors, ensuring broad compatibility with both new and existing graphics cards.

The fully modular cable design allows users to connect only the cables they need, significantly improving airflow and cable management inside the case. This results in a cleaner, more organized build with optimized cooling performance. Modular cabling is especially beneficial for mid-tower and compact cases where space efficiency matters.

A standout feature of the Pure Power 12 M 750W is its silent 120mm be quiet! fan, engineered for low-noise operation. Designed with high-quality bearings and optimized airflow blades, the fan ensures efficient cooling while maintaining whisper-quiet acoustics—even under load. This makes it an excellent choice for gamers and professionals who value silent PC performance.
