Reviews - Seasonic X-400 Fanless 400W
Greetings once again, good readers of mine. It's been a rather long time since I last got to test my mettle with a fanless power supply, but after several long months the wait is over. Ladies, gentlemen, aliens, llamas, today I give you the latest from Seasonic in the fanless X series 400 watt unit. This is exactly what you think it is, unless you thought for some inexplicable reason this was a toaster - a version of the original X-650 and X-750 units designed to run from nothing to full power without a fan. You will recall that the more powerful X series units were designed to be semi-fanless from the get go. Seasonic was able to do this by designing an extremely efficient platform that made good use of open space inside the unit. Like its big brothers, this unit is also certified for 80 Plus Gold. Our first stop on today's box tour is the back of the box, where there's a fair bit of marketing goodness. This is the side of the box, at a size large enough for you to read. This will tell you how many connectors there are, what protection circuitry is present, what the power limits of this unit are, as well as a few other pertinent specifications. Aha, more marketing.
Seasonic X-400 Fanless
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? The 80 PLUS certification has been around for a few years now. From being a minority certification, it has now become a “must have” for any power supply aspiring to half decent quality levels. To gain the 80 PLUS logo, a power supply must have been certified by an independent organisation, which checks yield at 20%, 50% and 100% load as well as its PFC (Power Factor Correction), which must be higher than 0.9 at 100% load which implies active correction. To recap, the yield (energy efficiency) is the ratio between the power delivered to the machine and that consumed by the network. A power supply that draws 400 watts to deliver 300 watts has an energy efficiency of 75%, or 100 watts electrical energy wasted.
