Seasonic Shows Off 1200 W Platinum Power Supply
More than eighteen months after it first debuted the P Series, Seasonic unveils its range topping SS-1200XP3 (where XP3 denotes a third generation product). Visually, the new power supply closely resembles the 1000 W version and the first generation 860 W version (now retired). Also similar is the fan employed by the new unit, being the same Sanyo Denki San Ace 9S that Seasonic employs across its premium product lines. The similarities do not stop here though, the unit boasts the same semi-fanless operation mode where the fan is engaged only at loads exceeding 30% of the PSU's rated output, also the customary 105° C rated Japanese capacitors are used throughout the unit. Seasonic also advertises this unit as a single +12V rail design, just like it did (and still does) with its first generation P Series products, in spite of the fact that they are quad-rail designs with OCP trip points set very high. Remains to be seen if that is the case with the 1200 W version as well.

Here in Brazil the 1000W has vanished... and i really like the looks. And tell that this PSU has good performance is a understatement.
As far as efficiency the 92% rating is at 50% power on 115Vac. With 240V it might require a higher load to see the same efficiency. It depends on the design and components used.

A higher voltage means slightly more efficiency as well...
I'm using the 1000w model, and the mix-color cable is a huge turn off.
however, the back of that (connectors) is exactly the same as mine as well as the hybrid switch lol
my fans rarely spin up (need i think 60+% power usage) and mine being a 1kw (overkill) stays cool, ive never felt it hot.

My guess is it won't show up until after it goes on sale. Long story short, Platinum certification (115V internals) requires 90% efficiency at 20% load, 92% efficiency at 50% load, and 89% efficiency at 100% load.
Until it shows up on the above website, it's efficiency claims may be fake.
FYI, Enermax has lots of 80+ Platinum certified PSUs reaching all the way up to 1500w:
