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.
