Sfx = sff?

[Turbonium]

If they're the same, then why have more than one type of notation?

Seriously confusing for a SFF newb such as myself.

Also: do SFF PSUs typically have higher rated wattages than Mini-ITX PSUs?

SFX is its own form factor. TFX is also a SFF specification. SFF is just shorthand for "small form factor". Many mini-ITX cases can take a regular-sized PSU.

I'll have to remember this link, for the next time someone says "mATX PSU" probably because Newegg uses that notation.
