An advanced high-power computer power supply (850 W) with a modular removable cable subsystem, serious efficiency, a platinum quality certificate and a 10-year warranty. Part of the 2023 Straight Power line, aimed at experienced gamers who are not in the habit of overpaying for secondary and useless jokes like addressable lighting. Straight Power 12 is a new generation of ATX 3.0 class power supplies designed for installation in modern gaming systems equipped with video cards with a single 16-pin PCI-E 5.0 power connector.
An experiment using several 6+2 pin adapters to power a 12+4 pin 12VHPWR connector, which is used in many video cards produced in 2022–2023, fully demonstrated the unviability of this idea. It turned out to be inconvenient, not particularly beautiful, plus the adapters often melted, causing panic among PC owners. Otherwise, this is the same be quiet! that is well known to all fans of be quiet! “platinum” power supply, which is characterized by the highest level of efficiency (efficiency 93%) with extremely low noise levels.
It is built on a high-quality full bridge topology with an LLC converter and a DC-DC converter, the circuit design uses exclusively heat-resistant 105-degree Japanese capacitors, and the main 12V line is capable of accepting 100% of the original power of the device. Active cooling of the power supply components is provided by a 135 mm Silent Wings fan on a hydrodynamic bearing, which automatically changes the rotation speed depending on the load and can operate in silent mode. According to the manufacturer, this model is the optimal choice for gamers and enthusiasts planning to assemble a completely silent assembly. It is also perfect for powering workstations related to machine learning, 4K/8K video rendering, and similar tasks that require high computing resources.

850W Be Quiet! Straight Power 12 Modular 80 Plus Platinum PSU BN337
80 PLUS® PLATINUM CERTIFIED Highly efficient operation Straight Power 12 850W is certified with 80 PLUS Platinum and an... moreenergy efficiency rating of up to 94%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation. FUTURE-PROOF YOUR SYSTEM Fulfills all ATX 3.0 specifications Straight Power 12 850W is an ATX 3.0 PSU and comes with both native integration of 2 12VHPWR connectors for next-generation PCIe 5.0 graphics cards, and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come. THE NEW STANDARD OF POWER For massive transient loads Straight Power 12 offers 850W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Straight Power 12 850W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards. SILENT WINGS FAN Provides virtually inaudible operation The high-end Silent Wings fan delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal power consumption. FLAWLESS COOLING CONCEPT For a longer lifespan The funnel-shaped fan inlet of the Straight Power 12 850W increases airflow while reducing unwanted turbulence for a higher cooling performance. The wire-free design inside allows the cool air to reach all components which ultimately leads to a longer lifespan. STATE-OF-THE-ART TECHNOLOGIES Rock-steady signal stability and efficiency With full bridge LLC Straight Power 12 850W offers advanced technologies, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation. JAPANESE 105°C CAPACITORS A testament to high quality Only premium components are used in Straight Power 12 850W. That is why this PSU features exclusively high quality Japanese capacitors. They are rated at 105°C for stability, reliability, and a long operating life. CONVENIENCE AND CONNECTIVITY Maximum utility Modular, sleeved cables of up to 100cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling - even in the largest PC cases.
