Computer caseA computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a personal computer.
Power supply unit (computer)Internal computer component that provides power to other componentsAn ATX power supply unit with top cover removedA power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
MicroATXIn computer design, microATX (sometimes referred to as mATX or µATX) is a standard motherboard form factor introduced in December 1997. The maximum size of a microATX motherboard is 9.6 × 9.6 in (244 × 244 mm). However, there are examples of motherboards using microATX designation despite having a smaller size of 244 × 205 mm (9.6 × 8.1 in). The standard ATX size is 25% longer, at 12 × 9.6 in (305 × 244 mm).
Desktop computerA desktop computer, often abbreviated as desktop, is a personal computer designed for regular use at a stationary location on or near a desk (as opposed to a portable computer) due to its size and power requirements.
Mini-ITXMini-ITX is a 170 mm × 170 mm (6.7 in × 6.7 in) motherboard form factor developed by VIA Technologies in 2001. Mini-ITX motherboards have been traditionally used in small-configured computer systems. Originally, Mini-ITX was a niche standard designed for fanless cooling with a low power consumption architecture, which made them useful for home theater PC systems, where fan noise can detract from the cinema experience.
Form factor (design)Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor.FlexATXFlexATX is a motherboardform factor derived from ATX. The specification was released in 1999 by Intel as an addendum to the microATX specification. It uses a subset of the motherboard mounting holes required for microATX and the same I/O plate system as ATX and microATX. FlexATX specifies that a motherboard be no larger than 9 × 7.5 in (229 × 191 mm), and can have no more than three expansion slots.
MotherboardA motherboard, also known as a mainboard, system board, logic board, and informally mobo (see § Nomenclature), is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.
Expansion cardIn computing, an expansion card, also known as an expansion board, adapter card, peripheral card or accessory card, is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes the design of the computer's case and motherboard involves placing most (or all) of these slots onto a separate, removable card.
IntelAmerican multinational technology companyIntel Corporation is an American multinational technology company headquartered in Santa Clara, California. It designs, manufactures, and sells computer components such as central processing units (CPUs) and related products for business and consumer markets.
AT (form factor)In the era of IBM compatible personal computers, the AT form factor comprises the dimensions and layout (form factor) of the motherboard for the IBM AT. Baby AT motherboards are slightly smaller, measuring 8.5" by 13". Like the IBM PC and IBM XT models before it, many third-party manufacturers produced motherboards compatible with the IBM AT form factor, allowing end users to upgrade their computers for faster processors.De facto standardA de facto standard is a custom or convention that is commonly used even though its use is not required. De facto is a Latin phrase (literally "of fact"), here meaning "in practice but not necessarily ordained by law" or "in practice or actuality, but not officially established".*As an Amazon Associate I earn from qualifying purchases.
