Seasonic 250W FLEX Power Supply/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 type of cooling mechanism used by a product, such as active fan‑based cooling, passive heat sinks, liquid cooling, or no active cooling. It indicates whether the device relies on airflow, conduction, or other methods to dissipate heat and helps users assess thermal performance and noise levels.

A brief statement indicating the edition or version of a product, such as "Reprint", "New Edition", or a numeric edition number like "2nd edition". It identifies which specific release of the item is being referenced.

Indicates whether the product includes an EPS 12V power connector, which is commonly used to supply additional voltage to high‑performance computer components such as CPUs and GPUs.

The physical dimensions of a fan unit, expressed as the number of fans and their individual diameter in millimetres (e.g., "2 x 120mm"). This attribute helps users understand the cooling capacity and compatibility with cases or other components.

The count and configuration of the +12 V power rails supplied by a computer power supply unit. Common values include "Single Rail", "Dual Rail", "Quad Rail" or combinations such as "Single/Multi Rail". This attribute helps users understand how many independent +12 V outputs are available for powering components, which can affect load distribution and reliability.

The highest electrical current that a power supply can deliver on its combined +12 V rail, expressed in amperes (A). It indicates the maximum load capacity of the +12 V output and is useful for comparing power supplies or determining if a unit can meet the needs of high‑power components.

The highest percentage of input electrical power that a device can convert into usable output power when operating on 230 V alternating current. It indicates the peak energy conversion performance and helps consumers compare how efficiently different models use electricity.

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.

Indicates the type of modularity a product offers, such as full modular, hybrid modular, or fully wired. The value describes how components can be added, removed, or replaced independently within the system.

The total number of electrical contacts in the ATX main power connector that supplies a computer system with power. Common values are 20+4‑pin (24 pins) and 24‑pin, indicating the standard ATX power interface used by motherboards and power supplies.

The form of packaging used for a product, such as box, blister pack, bag, or pallet. It indicates how the item is contained and protected during shipping and storage.

The electrical current supplied by the first +12 V rail in a power distribution system, expressed in amperes (A). It indicates how much current the rail can deliver to connected components and helps assess load capacity and thermal performance.

The overall dimension or measurement that identifies the size of a product, such as a frame, garment, electronic component, or container. It can be expressed as a single numeric value (e.g., 47 mm), a range (e.g., 50–60 cm), a volume (e.g., 700 ml), or a descriptive label like "One Size". The attribute helps customers compare and select items that fit their needs.

Indicates whether the product supports NVIDIA SLI or AMD CrossFire technology, allowing multiple graphics cards to work together for increased performance.
