240W TFX power cable for ThinkCentre

This 240W TFX internal power cable carries part number 54Y8849 and fits Lenovo ThinkCentre E73, M78, M82, M83, M92, M92P and M93 small-form-factor desktops. It delivers power through a 14-pin motherboard connector and a 4-pin CPU connector. The unit accepts 100-264V input and uses passive PFC. It is a non-modular replacement cable supplied new.

Suits owners replacing a failed TFX cable

The cable matches the original 14-pin and 4-pin layout used in the listed ThinkCentre models. It provides no 12V graphics connector, so systems needing a discrete GPU power feed cannot use it. Builders working on standard ATX chassis or boards with 24-pin and 8-pin CPU sockets should look elsewhere.

Check your motherboard pin count before ordering

Verify that your board uses a 14-pin main power header and a 4-pin CPU header. Confirm the chassis accepts a TFX form-factor supply. Ensure the 100-264V input range covers your local mains voltage. No modular cables are included, so the fixed harness must reach all required headers.

Questions about this item

Does my ThinkCentre need a 14-pin motherboard header and a 4-pin CPU power socket to use this 240W TFX supply?

Yes, the unit provides exactly one 14-pin motherboard connector and one 4-pin CPU power connector, matching the listed ThinkCentre models.

Will this 240W TFX PSU fit and power a ThinkCentre M78 or M93 that originally shipped with a 240W TFX unit?

It is listed as compatible with M78, M82, M83, M92, M92P, M93 and M93P small-form-factor desktops using the same TFX form factor.

How can I confirm the PSU is delivering power after installation?

The system should POST and boot normally; the motherboard receives power through the 14-pin connector and the CPU through the 4-pin connector.
