Be Quiet 850W Dark Power 12 - Full Modular Power Supply

The range of alternating current voltage that a power supply or charger can safely accept from its mains source, expressed in volts (V). It specifies the minimum and maximum input voltages compatible with the device, ensuring proper operation across different regions.

Indicates the types of components, devices or form factors that a product can support or work with. The value may describe supported power supply units, graphics card clearance, memory modules, operating systems, or other hardware specifications.

The classification of the mechanical bearing used in a fan or cooling component, such as ball, sleeve, fluid dynamic, hydraulic, magnetic levitation, or other specialized types. It indicates the internal design that determines load capacity, noise level, durability and suitability for specific applications.

The specific model or design of a fan used in a product, such as size (e.g., 80 mm, 120 mm), bearing type (e.g., fluid dynamic, rifle, ball‑bearing), noise level, and any special features like PWM control or RGB lighting. It helps users identify the fan’s physical characteristics and performance traits.

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

Indicates whether a product supports modular components or systems, such as modular power supplies, network switches, or other hardware that can be expanded or replaced with compatible modules.

A comma‑separated list of protective features that a product offers, such as resistance to dust, water, shock, heat, or other environmental factors.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
