be quiet! Straight Power 11 BN284

Hi-End power supply with a rated power of 850 W with advanced circuitry based on heat-resistant Japanese capacitors, a modular cable system and a virtually silent cooling system. It belongs to the upper price range and is part of the Straight Power line of advanced power supplies, which are distinguished by high quality performance and low noise levels. The power supply is certified according to the “80 PLUS GOLD” standard and is equipped with all modern protection mechanisms, so it can be trusted to power powerful and expensive components of the Core i9 + GeForce RTX 4080 level.

The declared efficiency of the power supply reaches 93%. be quiet! Straight Power 11 has 4 independent power lines (12 V), which makes it as reliable as possible. The circuitry is built using Japanese-made capacitors, a half-bridge LLC circuit and DC-DC converters, which are characterized by excellent stability and reliability even when the components are very hot. The main 12-volt line is capable of providing almost 100% of the total power of the device.

Active cooling of the power supply components is provided by a 135 mm Silent Wings 3 fan on a hydrodynamic bearing. It automatically changes rotation speed based on device temperature, and fan blades optimized for better airflow reduce turbulence, resulting in noise levels of just 25 dB above 90% load. And with a decrease in overall energy consumption, the fan blades rustle barely noticeably, without causing any discomfort.

An important feature of the model is the use of boards with wireless connections of components - the absence of unnecessary wiring has a positive effect on cooling. Fully modular wiring makes it possible not to limit yourself in matters of cable management, especially when it comes to a transparent or translucent case, the owner of which took care of the interior decoration and lighting. Built-in protection against overcurrent and power, overvoltage and undervoltage, short circuit and overheating, as well as an official five-year warranty from the manufacturer, allows you to look into the future with optimism, without particularly worrying about the safety of PC components.
