Seasonic Platinum Series Fanless 460 W 6

Seasonic Platinum Series Fanless 460 W Review

A Look Inside & Component Analysis »


The small package features a platinum-colored backdrop as a direct reference to the PSU's official efficiency certification. In the top-right corner resides the Platinum badge, and Seasonic's logo is located in the opposite corner. The middle of the front also has a photo showcasing the unit's front side. The PSU's capacity is highlighted against a black background found close to the bottom-right corner of the box.

One of sides has a photo of the unit's modular panel, while the other side has a list of the unit's technical characteristics and the power specifications table.

The top side only has the series description along with the EuP 2013 and Platinum badges. A multilingual features description is given on the opposite side.

The rear side provides some useful information about the official 80 Plus standard certifications and has some paragraphs that explain the PSU's most significant features. This side also has an interesting photo of the unit's internals and a statement by Seasonic: Their new fanless Platinum PSUs offer a couple new features in addition to all the features of the previous X-series units.


Like all Seasonic products, this one is adequately protected by packing foam. It is also stored inside a nice velvet bag, which makes the high price Seasonic asks for the unit a little more agreeable. We also found a notification label on the PSU informing us that it should be installed with the top ventilation cover facing up. For everyone that forgot some of the basics behind physics: hot air is lighter than cold air and travels up. Installing the PSU with the top ventilation cover facing down would trap all the hot air inside the PSU, and trapped hot air creates overheating issues.

A nice, large pouch holds what few modular cables there are and the AC power cord. The bundle is pretty rich and includes several Velcro straps, some zip ties, a set of fixing bolts, a case badge, and the user's manual.


The enclosure looks like Swiss cheese. It is full of ventilation holes to allow for optimal airflow. We find a useful on/off switch at the front, besides the essential AC receptacle. The decals on the sides are very small because the vents occupy most of the real estate. The rear side has plenty of modular sockets and connecting everything will even leave you with a spare 8-pin socket, which would allow you to increase your EPS or PCIe cable count if you were to get an additional one. The specifications label is installed on the bottom side, while the top side of the unit grants a clear view the internals through all the holes it features.
