The Seasonic X-Series 850W supply is a plain design with a black finish and stickers on the sides of the chassis. The paint work is deep and it will fit into a variety of systems without problem.

The 120mm fan is hidden behind a black grill. We will take a closer look at this later in the review.

One side of the power supply is fully vented to improve air flow. At the side is a power switch and connector.

The X-Series 850W has several rows of ports for the modular connectors. These are all clearly labelled to avoid confusion. There is a sticker bottom which indicates that the fan will only spin when a certain temperature threshold is met.
