TFX (85 x 65 x 140 mm)

Seasonic has already been selling 300W/350W TFX and extended-depth FlexATX PSUs and 400W/500W 1U/2U PSUs that are 80+Gold certified for a few years, but this is their first update in the SFX and the regular-size FlexATX departments after quite a while and the SSP-300SFG is their first 80+Gold SFX unit. The TFX unit also has notably shorter depth; indeed 150mm is the shortest for TFX PSUs that I have previously noted before.
Other than the obvious differences imposed by different form factors they seem all identical. Single combined 12V rail, no PCIe 6/8pin connectors, DC-DC design, Haswell-ready.

The SFX is gold-rated and can do all 300W on 12V so that's a step in the right direction. Now they just need to give it a nice matte black paint job like the TFX 350, up the wattage, give it modular connectors, and make it as quiet as possible :)

I'm not sure there's enough room on the back of a FlexATX PSU for modular connectors without losing even MORE airflow area.

There absolutely isn't. You'd need connectors other than the Molex MiniFit series that can still carry enough current to comply with the ATX standard, but there is a separate thread for extended discussion on that ;)
