How to use
Shut down the PC and disconnect all cables before beginning. Open the desktop chassis according to the manufacturer’s service instructions for your Lenovo model. Disconnect the existing power supply cables from the motherboard, drives and other components, noting connector positions. Remove the old TFX unit, then install the Lenovo 240W TFX PSU (54Y8874-RFB) in the same orientation, secure it with the appropriate screws or clips, and reconnect each connector to its matching header. Close the chassis, reconnect external cables, and power on the system to verify normal operation and stable booting.
Usage recommendations
Confirm that your Lenovo model supports the TFX form factor and that total system power draw does not exceed the 240W rating. Use the specified connectors only in their intended locations and avoid modifying cables. For systems with higher power requirements or discrete high-performance graphics cards, consider a higher-wattage or different form factor PSU. If unsure, consult Lenovo service documentation or a qualified technician to ensure compatibility and safe installation.
