Different sizes of Micro ATX

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.

There's a little site called 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.
