VISUAL TOUR
The first glance when the PSU is removed from its soft pouch shows two distinct
things:
- The casing is completely vented, with hex holes on top that are bigger than
the ones used for the back panel exhaust. It's basically an expansion of the
intake fan grill used on fan-equipped Seasonics.
- A big notice tells to "install with the ventilation top cover facing
UP". This is the side where the 120mm fan is mounted on the higher power
X-series models; it's normal for the PCB to be on the top side of the PSU,
with components hanging down from it. So Seasonic means for the X-400 to be
mounted turned over, 180° from the norm. Note that there are enough tapped
mounting screw holes so that the PSU can be mounted either way, so if you
disagree with Seasonic's advice for your PC setup (and there are so many different
types of cases that use ATX PSUs these days), you can try it the other way
without any hacking.
This worthy of further discussion, later.
One other observation is that the X-400 is a complete departure from the norm
in that it's a lightweight, only a little over 3.5 lbs without cables. This
is in stark contrast to every other fanless ATX PSU reviewed in the past eight
years — they have been very heavy, easily 5~6 lbs on average, with massive
amounts of extruded aluminum, some of which is used for the casing.
The side which holds the fan in higher power X models has the same
basic grill, expanded across most of its area, and a notice calling
for the unit to be installed that side up.
The modular cables are nicely finished.

Like other X-series models, the X-400 casing is a departure from
the normal dual C-shaped clamshell. The metal is thicker and is fitted together
tightly with great precision — though Seasonics have always been excellent
in this regard. The black and gold color scheme continues in the paint job and
labels. The X-400 Fanless exudes quality in every way.
It's well ventilated on almost every side...
...even the normally unvented "bottom". The same smart-keyed
output connector scheme is used as in the X-650, but fewer of them, reflecting
the X-400's lower output rating.
The label is in several languages and boasts a myriad of safety approvals.
