How to use

Power off the computer and disconnect the power cord before beginning installation. Remove the chassis cover and locate the existing power supply; disconnect all power connectors from the motherboard, drives and peripherals. Unscrew and remove the old unit, then position the Lenovo 210W TFX PSU into the chassis aligning mounting points. Secure the unit with screws, connect the main motherboard connector and any auxiliary power leads to drives and peripherals, replace the cover and reconnect the external power cord. Power on the system and verify stable boot and component operation.

Recommendations

Ensure the system chassis supports the TFX form factor and that connected components’ combined power draw remains within the 210W rating. Use only compatible connectors and avoid forcing mismatched plugs. If the system exhibits instability after installation, recheck connections and consult system documentation or a qualified technician.
