Cooler Master V650 Gold V2 Fully Modular ATX PSU

The efficiency rating expresses the percentage of input power that a product converts into useful output, indicating how well it uses energy compared to similar models. A higher value means less waste and lower operating costs.

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 physical diameter of a fan, expressed in millimeters or inches. It indicates the size that determines compatibility with chassis, heatsinks, and mounting brackets.

The electrical current drawn by a device when powered, expressed in amperes (A). It indicates how much current the product consumes from its power source during normal operation and can be used to assess compatibility with power supplies or USB ports.

The range of electrical voltage that a device can safely accept from its power source, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the product, covering both AC and DC inputs where applicable.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The total count of physical SATA interfaces available on a product, including all versions (SATA I, II, III). This value indicates how many storage devices can be connected simultaneously via SATA ports.
