Be Quiet! Straight Power 12 1200W - Premium ATX 3.0 Power Supply

The Be Quiet! Straight Power 12 1200W delivers future-proof power with 80 PLUS Platinum certification achieving up to 93.7% efficiency. This fully modular ATX 3.0 power supply combines high-performance operation with virtually inaudible cooling, making it the optimal choice for demanding PC builds.

ATX 3.0 Compliance with PCIe 5.0 Support

Designed for next-generation systems, this PSU features native integration of 2x 12VHPWR connectors for PCIe 5.0 graphics cards alongside 4x PCIe 6+2-pin connectors for current GPUs. This versatile connectivity ensures compatibility with both existing and upcoming high-end components.

Exceptional Power Handling

The Straight Power 12 provides 1200W continuous power through one massive 12V rail. It handles power excursions up to double its rated capacity, ensuring stable operation during transient loads from modern processors and graphics cards. This capability is essential for systems with high-power GPUs that demand sudden power spikes.

Silent Wings 135mm Fan Technology

Equipped with Be Quiet!'s proprietary Silent Wings 135mm fan featuring an advanced fluid-dynamic bearing and 6-pole motor. The optimized fan blade design delivers high airflow while maintaining near-silent operation - measuring just 9.4 dB(A) at 20% load and 32.2 dB(A) at full load. The funnel-shaped fan inlet increases airflow efficiency while reducing turbulence.

Premium Component Quality

Built exclusively with Japanese 105°C-rated capacitors for maximum stability and reliability. Full bridge LLC technology ensures rock-steady signal stability, superior voltage regulation, and minimal ripple noise. The wire-free internal design optimizes cooling efficiency across all components, extending operational lifespan beyond 100,000 hours MTBF.

Fully Modular Cable Management

Sleeved modular cables extend up to 100cm, simplifying installation and reducing case clutter. The comprehensive connector array includes 1x P4+4 CPU, 1x P8 CPU, 2x 12VHPWR, 4x PCIe 6+2-pin, 9x SATA, and 2x PATA connections. Improved airflow from organized cabling enhances overall system cooling performance.

Comprehensive Protection Suite

Features complete protection circuitry including OTP, OCP, OPP, SCP, OVP, UVP, and SIP. These safeguards protect your components from temperature extremes, power surges, short circuits, and voltage irregularities. Backed by a 10-year manufacturer's warranty for long-term confidence.
