Seasonic X-400 Fanless SS-400FL - Power Supply Circuits

For fanless unit X-400 is a bit unusual: no walls, as expected, perforated, but where’s the huge heat sink that forms the top cover? Without a doubt, Seasonic X-400 Fanless could surprise : externally it is more like a normal block, which forgot to put a fan than a model that could be given without the fan to four watts of power. However, he – can. Moreover, with the X-400 Fanless shows excellent electrical characteristics and features a fully modular cables, and enthusiasts who want to get extremely quiet power supply with a guaranteed blow through mesh top cover unit can be easily installed on a low-speed fan.

The last as strange as it sounds, can be quite interesting: the quiet power supply low power comes not so much, fanless system is causing many users fear for adequate cooling and uncertainty in long-term reliability. Setting the same fan with a speed of 500 rev / min and will ensure a reliable cooling (even a fan is clearly more efficient natural convection), and get their hands on the most quiet power supply with sufficient power not only for the HTPC, but for the average gaming computer class.
