Lenovo Power Supply Buying Guide: Use the machine type and existing unit label
Record the complete ThinkCentre model, machine type and the part or FRU number on the existing supply. Lenovo’s Parts Lookup can help identify parts for a particular machine. Similar family names can include several case formats and internal designs. Match the actual unit rather than buying from the desktop brand alone.
Connector count and wattage are separate checks
The examples include 14-pin plus 4-pin and 24-pin plus 4-pin supplies. These are not interchangeable simply because they carry the Lenovo name. Compare connector pinout, cable reach and the motherboard’s requirements. A higher wattage rating does not correct the wrong connector or the wrong physical size.
Confirm fit and installation arrangements
Measure the unit, check mounting points and identify the SFF or other case format. Share clear photos of the old supply label and connectors when requesting a match. Leave internal power-supply repair to a qualified technician. Confirm the selected unit’s warranty and whether fitting is included before ordering.
