Show Product Description

The be quiet! Straight Power 11 Platinum 1000W BN309 Power Supply sets new standards for silent operation and outstanding efficiency, making it an exceptional choice for high-end computing environments. Designed in Germany and engineered for reliability, this PSU is perfect for professional offices, gaming setups, creative studios, and advanced home use—where power, silence, and flexibility are paramount. At its core, the Straight Power 11 Platinum delivers a continuous output of 1000 watts and a peak of 1070 watts, easily supporting overclocked CPUs and multi-GPU systems. With an 80 PLUS Platinum certification, it offers up to 94.1% efficiency, significantly reducing energy costs and heat output. The power supply features the virtually inaudible Silent Wings 3 135mm fan, equipped with advanced 6-pole motor technology and a funnel-shaped intake for optimal airflow, keeping your system cool and quiet even under heavy load. Noise levels remain impressively low, starting at just 7.8 dB(A) at 20% load. One of the key innovations is the wire-free DC-side design, which maximizes cooling performance and extends component lifespan to up to 100,000 hours at 25°C. The fully modular cable management system allows you to use only the cables you need, ensuring a clean, organized build and simplifying future upgrades or maintenance. Technical features include four separate 12V rails, six PCI-E 6+2 connectors for high-end and overclocked graphics cards, eleven SATA connectors, and four PATA connectors—making it ideal for demanding workstations, gaming rigs, and systems with extensive storage requirements. Premium Japanese capacitors rated at 105°C ensure stable and reliable power delivery under the most challenging conditions. Comprehensive electrical protection is built in, including OCP, OVP, UVP, SCP, OTP, OPP, and SIP, safeguarding your components against overloads, surges, and other electrical hazards. The PSU complies with global energy and safety standards, including ENERGY STAR 7.0, ErP, RoHS, CE, TÜV, and CB certifications. Maintenance is straightforward: periodically clear dust from the power supply using compressed air, avoid exposure to moisture or extreme heat, and ensure installation in a well-ventilated location for optimal performance.
