That isn't SFX that is standard ATX size. 150x150x86mm or close too. The standard SFX is 125x100x63.5mm but only Silverstone & Lian Li produce them and I have been burnt before with those and their build quality so if Seasonic or Superflower came out with something then I would jump on that tbh.
Ah ok, its actually my PSU, it is quite compact, hard to imagine them even smaller, i'm not sure who its made by, i think its Seasonic.
This is the PSU in my mini-ITX system:
