Lenovo 180W SFF 14-pin PSU

The Lenovo PS-3181-02 is a 180-watt small-form-factor power supply built for compatible Lenovo desktops. It uses a 14-pin connector layout that matches specific SFF chassis designs. This unit suits IT teams maintaining fleets of supported Lenovo models. Buyers who need higher wattage or standard ATX pinouts cannot use this part.

商品問答

Will the 14-pin connector need to be replaced during the life of this PS-3181-02 unit?

The 14-pin connector is a fixed part of the 180 W PS-3181-02; if it wears or is damaged the whole power supply must be replaced.

What limits sustained output first on this 180 W SFF power supply?

The 180 W rating is the ceiling; continuous draw at or near that level will hit the unit's thermal and current limits before any other factor.
