The Seasonic X-Series 1250W supply is very attractively designed, with deep black paint on all panels. The top of the chassis has a gold panel with a large fan underneath. The X-Series is fairly resistant to finger prints and minor scratches. It measures L190 x W150 x H86 mm.

The 120mm fan is hidden behind the grill, but we will take a closer look shortly when we take the unit apart.

One side of the power supply is fully vented to help with air flow. There is a power switch and connector at the side.

There are several rows of ports for the modular cables as shown above – these are all clearly labelled to ensure even the most inexperienced user won't run into installation problems. There is a sticker on the chassis which highlights the dual switch operation – hybrid and normal. This sticker can be removed before use.

104A can be delivered to the +12V rail, which is more than enough for any system build.
