Seasonic, being both an OEM and retail manufacturer, has three current PSUs with the coveted Gold certification, and the latest does so in spite of the the slight handicap imposed by using modular connectors.
To be released at COMPUTEX this year, the Seasonic X-Series will be launched with 550W, 650W, and 750W capacities, and thus providing around 90 per cent efficiency in the range of watts pulled by most reasonably high-end rigs.
Rated to 50C at the stated wattage, the X-Series will also be available in fully-modular form in H2 2009. A single Sanyo Denki 120mm fan cools the unit, and full-retail models will feature a brand-new fan-controller, we were told.
Expect the X-Series to challenge the likes of Enermax's Revolution when out later on this year. Pricing, though, will be confirmed during COMPUTEX.
