Factores de forma de los ordenadores
En informática, el factor de forma es el nombre que se utiliza para denotar las especificaciones de una placa base como las dimensiones, tipo de fuente de alimentación, situación de los orificios de montaje, el número de puertos en el
panel posterior, etc.. Específicamente, en la industria de los PC compatibles, los factores de forma estándar asegurarán
de que las piezas son intercambiables entre proveedores y generaciones de tecnología

Obsolete, see Industry Standard
Architecture. The IBM Personal
Computer XT was the successor to the
original IBM PC, its first home
computer. As the specifications were
open, many clone motherboards were
produced and it became a de facto
standard.
Obsolete, see Industry Standard
Architecture. Created by IBM for the
IBM Personal Computer/AT, an Intel
80286 machine. Also known as Full AT,
it was popular during the era of the Intel
80386 microprocessor. Superseded by
ATX.

IBM's 1985 successor to the AT
motherboard. Functionally equivalent to
the AT, it became popular due to its
significantly smaller size.
Created by Intel in 1995. As of 2007, it
is the most popular form factor for
commodity motherboards. Typical size
is 9.6 × 12 in although some companies
extend that to 10 × 12 in.
Created by the Server System
Infrastructure (SSI) forum. Derived
from the EEB and ATX specifications.
This means that SSI CEB motherboards
have the same mounting holes and the
same IO connector area as ATX
motherboards.

FlexATX
Intel 1999
228.6 × 190.5 mm max.
Mini-ITX
VIA 2001
170 × 170 mm max.
A smaller variant of the ATX form
factor (about 25% shorter). Compatible
with most ATX cases, but has fewer
slots than ATX, for a smaller power
supply unit. Very popular for desktop
and small form factor computers as of
2007.
Mini-ATX is slightly smaller than
Micro-ITX. Mini-ATX motherboards
were design with MoDT (Mobile on
Desktop Technology) which adapt
mobile CPU for lower power
requirement, less heat generation and
better application capability.
A subset of microATX developed by
Intel in 1999. Allows more flexible
motherboard design, component
positioning and shape. Can be smaller
than regular microATX.
A small, highly-integrated form factor,
designed for small devices such as thin
clients and set-top boxes.

Used in the VIA Android PC
A standard proposed by Intel as a
successor to ATX in the early 2000s,
according to Intel the layout has better
cooling. BTX Boards are flipped in
comparison to ATX Boards, so a BTX
or MicroBTX Board needs a BTX case,
while an ATX style board fits in an
ATX case. The RAM slots and the PCI
slots are parallel to each other. Processor
is placed closest to the fan. May contain
a CNR board.

List of computer PSU form factors
ATX PS/2
This is by far the most popular PSU form factor and is often called the “standard ATX PSU”
Standard dimension for this form factor is: 150mm (W) x 86mm (H) x 140mm (D)
PSU with depth longer than 140mm can still be considered as an ATX PS/2 model

ATX PS/3
This form factor is compatible with ATX PS/2, the only difference is the shorter depth. Many have also called this
the “Micro ATX” PSU form factor, which is incorrect as no such standard exists for power supplies.
Standard dimension for this form factor is: 150mm (W) x 86mm (H) x 100mm (D)
The depth for this form factor may vary from 100mm up to 139mm

SFX
This form factor is popular with small computer cases and is also often wrongly referred to as “Micro ATX” power
supplies. Because this standard is smaller than ATX PS/2 in all dimensions, it can be used in cases that
support ATX PS/2 with simple adapters or brackets. Some retail SFX power supplies are sold with adapters
included.
Standard dimension for this form factor is: 125mm (W) x 51.5mm (H) x 100mm (D)
There are variations for this form factor that have longer depth.

Flex ATX
This form factor is often used in small computer cases and is sometimes wrongly referred to as “Mini-ITX” PSU.
Standard dimension for this form factor is: 81.5mm (W) x 40.5mm (H) x 150mm (D)
There are variations for this form factor that have longer depth.

TFX
This form factor is commonly used in computer cases with limited height or non-standard shapes. It has similar
proportions to Flex ATX but is bigger in all dimensions.
Standard dimension for this form factor is: 85mm (W) x 65mm (H) x 175mm (D)
There are models with varying depth, but usually shorter than 175mm

PS/2 mini redundant
This form factor has similar dimension to ATX PS/2, but because it requires hot-swap capability, the mounting
holes to computer cases are different. Usually cases designed to fit PS/2 mini redundant PSUs have separate
bracket to support ATX PS/2 as well.
Standard dimension for this form factor is: 150mm (W) x 85mm (H) x 200mm (D)
There are models with varying depth, usually around 200mm
