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.
