Are all ATX PSU's the same size?

[refllect]

This case says it takes standard ATX PSUs then on the bottom it says max PSU length 140mm which is only 5.5 inches. Are standard ATX PSUs this length?

ATX PSU's only vary by the LENGTH.

*All you need to do is check that the PSU is no longer than 140mm.
