High-Efficiency ATX 3.0 Power Supply Unit for GPU-Accelerated Towers with the BN339
BN339 is a 1200W ATX-form-factor PSU engineered for modern workstation and tower builds that combine high-core-count CPUs with power-dense GPUs. As an ATX 3.0 platform, BN339 is designed for transient load behavior typical of PCIe 5.0-class graphics, while maintaining stable multi-rail delivery for mixed CPU and accelerator profiles in content creation and technical computing systems.
The fully modular cabling of BN339 simplifies airflow planning and serviceability in high-component-density chassis. Dual 12VHPWR outputs and additional 6+2-pin PCIe connectors support multi-GPU configurations and heterogeneous expansion without adapters, while the 24-pin ATX plus EPS12V feeds align with current workstation motherboard power topologies. For storage-heavy towers, the SATA connector density enables large local datasets and scratch arrays with clean power segmentation.
Why Choose the BN339?
BN339 provides an efficient density-to-performance balance for enterprise-grade towers where electrical margin, connector scalability, and predictable thermals are required. With 80 PLUS Platinum efficiency and an ATX 3.0 control design, BN339 supports sustained utilization while reducing wasted power and heat, improving platform stability and simplifying capacity planning for GPU-focused deployments.
Be Quiet! designs for low-noise, controlled thermals and long-term reliability, combining an actively cooled 135mm fan profile with comprehensive protection logic including OCP, OVP, UVP, OPP, and OTP. This engineering approach aligns with modern data center and lab standards where electrical safeguards, acoustic control, and consistent operation across 0–40°C are operational requirements.
