FlexATX is a PC motherboard form 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 9.0 x 7.5" (229 x 191 mm), and can have no more than 3 expansion slots.
