Seasonic X-400 Fanless (SS-400FL)
 

After launching the X-Series, its first 80 PLUS Gold power supplies in September 2009, Seasonic announced a whole range at Computex, going from 400 to 1200 watts. The least powerful versions, the 400 to 460 watt supplies, are both fanless, which is a first among 80 PLUS Gold power supplies. Promising on paper, will the quality of these power supplies be confirmed in practice?
