In the power supply realm, when consumers think of quiet and efficient power supplies one of the first company that comes to mind is Seasonic. Over time, Seasonic has been one of the most prolific brands covered in our reviews and today we have our second crack at a fanless Seasonic branded unit. This review in particular covers Seasonic’s smallest wattage new addition to their fanless lineup of power supplies; the X-400FL Platinum (SS-400FL2 Active PFC F3).
Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus, and their reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, Corsair, PC Power and Cooling, and of course under its own Seasonic brand.
For a long time, Seasonic has been considered by many enthusiasts to be one of the premier manufacturers of quiet power supplies. Oddly though, prior to today’s entry, we have seen just one truly fanless unit from Seasonic (the X-400FL). Today though, we get a second shot at this type of unit and it is again a 400W unit so we should be able to draw some easy comparisons in how things have changed since we saw the last unit. From the outset, the only immediately obvious change in today’s X-400FL Platinum is that it is rated as being more efficient than the previous unit’s 80 Plus Gold rating. However, it has been almost 3 years since we saw that previous unit so there certainly exists the possibility, or perhaps even the hope, that today’s unit does much more than just come in a bit more efficient. Before moving on, let’s see what Seasonic has to say about this unit:

Unlike with the X-400FL launch, there is little that Seasonic has actually said about this unit. So, let’s move on to see what we have to look forward to when we purchase the X-400FL Platinum in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
