Still, I have to remind you that building computers with fanless PSUs requires some experience. You shouldn’t try to remove all the fans from your system case because they cool not only the components they are actually attached to, but also other...

Folks, Seasonic's come up with another winner. They've taken the X series platform, removed the fan, fixed the lingering issues with the platform, and come up with an outstanding fanless unit that's sure to please anyone looking for a good...

Seasonic is the first manufacturer to put low power fanless 80 PLUS Gold power supplies on the market. Doing this is one thing, but doing it well is quite another and here Seasonic has put in a faultless performance. In terms of organization first of...

The new Seasonic X-400 Fanless is an impressive power supply. During our tests it achieved efficiency always above 87%, peaking 91.5%, voltages very close to their nominal values (3% regulation instead of the traditional 5% regulation), and extremely...

Before even beginning to sum this unit up it is important to remember one thing; the X-400FL is a niche product meant for only a small subset of users. Niche products often are more expensive than more broadly applicable solutions for various economic...

It is often the case that the lower rated models in a power supply product family feel like cheap recreations of their higher specification versions. Using components which are nowhere near the same class, cutting corners in build quality and...

Expectations ran high for the X-series 80 Plus Gold Seasonic power supplies, but our first reaction to the X-400 Fanless was admittedly less than enthusiastic. With the X-series already fanless to ~200W load and extremely quiet even after the fan...

No podemos decir otra cosa que nos encontramos ante unos de las mejores marcas de fuentes a nivel mundial; desde la calidad de fabricación hasta los acabados de la fuente en sí, son perfectos. Respecto a la regulación de voltajes,...

135 Euro sind ein stolzer Preis für ein 400-Watt-Netzteil. Das X-400FL ist dank völliger Geräuschlosigkeit und hervorragender Messwerte aber jeden Cent...

Mit dem X-400FL hat Seasonic ein technisches Spitzenprodukt auf den Markt gebracht. Die Qualität des Innenraums lässt nahezu keinen Grund zur Kritik, was nicht zuletzt an einigen technischen Innovationen wie zum Beispiel die Platzierung der...

Uno degli argomenti su cui ci siamo soffermati, durante il colloquio con Nils Stallmach, è stato il posizionamento ideale di un prodotto come il Seasonic X-400 Fanless: effettivamente le applicazioni sono molto più di quelle che si potrebbero...

De Seasonic heeft met de X-400 voeding een bijzondere en gedurfde voeding afgeleverd. De specificaties en testresultaten zijn prima in orde, maar zijn niet het meest interessante van deze voeding. De door Seasonic uitgedachte passieve koelconstructie...

Passive strømforsyninger er et genialt konsept. Men, etter å ha testet nesten 100 strømforsyninger totalt, der bare 4 av dem har vært vifteløse, har jeg aldri følt at konseptet har vært godt nok. Silverstone imponerte...

Mit dem Seasonic SS-400FL ist uns das erste Netzteil in die Hände geraten, dass passiv gekühlt wird und dabei nicht von dicken Aluminiumkühlern auf dem Netzteilgehäuse geziert wird. Ermöglicht wurde dieses Konzept vor allem...

A nova Seasonic X-400 Fanless é uma fonte de alimentação impressionante. Durante nossos testes ela apresentou eficiência acima de 87% (atingindo até 91,5%), as tensões ficaram muito próximas de seus valores nominais...

Das Netzteil X-400 Fanless von Seasonic ist ein echtes Goldstück. Es ist nicht nur 80+ Gold zertifiziert, sondern auch von uns mit einem Gold Award ausgezeichnet. Wer mit nur einem PCI-E 6+2-Pin Stecker auskommt ist mit diesem Netzteil bestens...

Seasonic est le premier à proposer des alimentations 80 PLUS Gold de faible puissance et fanless. Le faire est une chose, le faire bien en est une autre et Seasonic fait ici un quasi sans faute. En terme d’agencement tout d’abord,...

Das Seasonic X-400FL kann im Test voll überzeugen. Es punktet durch einen hohen Wirkungsgrad, der insbesondere in dieser Leistungsklasse vorher nicht mal annähernd erreicht wurde. Im Betrieb arbeitet es absolut lautlos, nicht das leiseste...
