Small form factor ( abbreviated: SFF[ 1]) is a term used for desktop computers and for some of their components, chassis and motherboard, to indicate that they are designed in accordance with one of several standardized form factors intended to minimize the volume and footprint of a desktop computer compared to the standard ATX form factor.
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. [ 1][ 2] 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 ...
Small Form-factor Pluggable. Small Form-factor Pluggable connected to a pair of fiber-optic cables. Small Form-factor Pluggable ( SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific ...
In computing, the motherboard form factor is the specification of a motherboard – the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. Specifically, in the IBM PC compatible industry, standard form factors ensure that parts are interchangeable across competing vendors and generations of ...
M.2, pronounced m dot two[ 1] and formerly known as the Next Generation Form Factor ( NGFF ), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the Mini SATA ( mSATA) standard and the Mini PCIe ( mPCIe) standard.
A 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.
Form factor (electronics) In electronics or electrical engineering the form factor of an alternating current waveform (signal) is the ratio of the RMS ( root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to ...
This smaller form factor is similar to that used in an HDD by Rodime in 1983, which was the same size as the "half height" 3½" FDD, i.e., 1.63 inches high. Today, the 1-inch high ("slimline" or "low-profile") version of this form factor is the most popular form used in most desktops.
