The Seasonic X Series 660W power supply ships with a paper wrap around it explaining that the fan will be inactive at less than 20% load.
The unit itself is very attractive, nicely finished, yet understated to suit a variety of windows case systems. The paintwork is deep and will withstand rough handling over time.
The 120mm fan is hidden behind a black grill without Seasonic labeling visible.
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 660W has several rows of connectors available for the modular cabling. These are all labeled for ease of installation. There is a ‘Temperature Activated Fan – Rotates only when required' sticker bottom right.
