Mini-ITX Addendum Version 1.1 To the microATX Motherboard Interface Specification Version 1.2

3 Power Supply Information

Provided the very different needs of the platforms that fit in the small desktop form

category, this specification does not attempt to define a standard for the power supply

to match with the Mini-ITX motherboard specification. Instead it recommends that

manufacturers consider using a:

• SFX, TFX or FlexATX are available power supply form factor for chassis

greater than 5 liters

• External power adapter for chassis less than 5 liters

Refer to the microATX Motherboard interface Specification for information on power

supply requirements.
