Hewlett Packard Enterprise 1200W 1U PSU

The official efficiency certification level awarded to a power supply or other electrical device that meets the international 80 Plus standard, indicating superior energy efficiency compared to non‑certified products. Typical values include Bronze, Silver, Gold, Platinum and Titanium.

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

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 ratio of real power to apparent power in an electrical system, expressed as a unit‑less number between 0 and 1. It indicates how efficiently the device converts supplied voltage into useful work; values closer to 1 mean less reactive power and higher efficiency.

The physical configuration or design of a power supply unit, such as ATX, TFX, SFX, or 1U. It indicates the dimensions and mounting options that determine compatibility with computer cases and other hardware.

The primary purpose of a product, indicating its main intended use or target market segment (e.g., "Gaming", "Office", "Travel"). It helps customers quickly identify whether the item matches their needs and can be used for filtering or categorization across different product categories.

The maximum electrical power that a product can consume or deliver during its operation, expressed in watts (W). It represents the peak power requirement or output of the device and is useful for sizing power supplies, estimating energy usage, and comparing performance across similar products.
