Antec EarthWatts Gold Pro 550W Semi-Modular Power Supply

The efficiency certification level of a power supply unit, indicating the minimum percentage of input power that is converted to usable output at various load levels (e.g., 20%, 50%, 100%). Common ratings include "80 Plus", "80 Plus Bronze", "80 Plus Silver", "80 Plus Gold", "80 Plus Platinum" and "80 Plus Titanium". The value helps consumers compare energy efficiency and potential operating costs of different power supplies.

A comma‑separated list of extra functions or characteristics that a product offers, such as special modes, connectivity options, or unique technical capabilities. The values are typically short phrases and may include multiple items for a single product.

The colour or combination of colours that a product’s outer shell or enclosure 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 case for consumers.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

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.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indicates the type of cable configuration a power supply offers: fully modular, semi‑modular, or non‑modular. A value of "Modular" means all cables can be detached and reconnected; "Semi‑Modular" indicates that some cables are detachable while others remain permanently wired; "No" (or "Non‑Modular") signifies that all cables are fixed to the unit.

The total count of Molex power connector ports present on a product, expressed as an integer without units. This value indicates how many Molex interfaces are available for connecting peripherals or components that require this type of connection.

The pin configuration of the power connector(s) used by a motherboard, expressed as a textual description such as "4 + 8-Pin" or "4-Pin x 2". It indicates how many pins are present in each connector and whether multiple connectors are required for proper operation.

The sound intensity produced by a product during operation, expressed in decibels with A‑weighting (dB(A)). This value indicates how loud the device is and helps users assess suitability for quiet environments or noise‑sensitive settings.

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 number of individual units contained within a single package or bundle. This value helps customers understand how many pieces they receive when purchasing the product, and it is useful for inventory, shipping, and comparison purposes.

The total number of physical PCI‑Express (PCI‑E) slots available on a product, such as a motherboard or expansion card. This value indicates how many separate PCI‑E interfaces can be used to install graphics cards, network adapters, storage controllers, or other expansion modules.

The arrangement of pins on a PCI‑Express connector, indicating how many power and data pins are present (e.g., "6+2-Pin", "8-Pin", "12+4-Pin"). This attribute helps determine compatibility with motherboards, GPUs, or other expansion cards that require specific pin counts for proper operation.

The electrical power rating of a product, expressed in watts (W). It indicates how much energy the device consumes during operation or how much power it can deliver to connected equipment.

The linear measurement of a power supply unit from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the PSU is and can be used for fitting, compatibility, or spatial planning.

The physical form factor of a power supply unit, indicating its size and mounting configuration (e.g., ATX, SFX, TFX). This attribute helps determine compatibility with computer cases and other hardware components.

The number of times per second that a display updates its image, expressed in hertz (Hz). It indicates the smoothness and responsiveness of motion on the screen; higher rates generally provide a more fluid visual experience.

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.

A list of formal recognitions, compliance marks, or industry standards that a product meets. Each entry may be a single certification (e.g., "RoHS", "CE") or a group of related certifications separated by commas (e.g., "CE, FCC, RoHS"). The attribute captures all applicable regulatory, environmental, safety, and quality approvals for the item.

The electrical potential difference that a device is designed to accept from its power source, expressed in volts (V). It indicates the nominal operating voltage for the product and helps users verify compatibility with local mains or battery supplies.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
