Different sizes of Micro ATX

2

A Case says it allows for MicroATX, with dimensions 9.6in x 9.6in but a motherboard is MicroATX, with the dimensions 9.6in x 8.8in. Will the motherboard still work with the case? as they are both MicroATX

Also is a different PSU needed for a microATX motherboard than an ATX one?

The max size of a MicroATX motherboard is 9.6in x 9.6in but they can be much smaller (6.75 in x 6.75 in according this Wikipedia article).

They use the same power supply connectors as the regular ATX motherboards.

so they are both compatible? – Jonathan. – 2009-10-19T19:32:35.153

Yes, they are. Give us the brand and model of the case and the motherboard if you want to be 200% sure. – Snark – 2009-10-19T19:34:29.877

There's a little site called http://www.formfactors.org/ that covers this. A couple screw holes are optional, the actual width is variable up to a limit based on the number of slots provided. The smaller board will mount and fit in the 9.6 x 9.6 space in the case.
