Who this suits and who should look elsewhere

System maintainers repairing or upgrading the listed ThinkCentre towers will find a direct-fit replacement. Builders assembling custom PCs or owners of other desktop families should look elsewhere because the connector layout and mounting are specific to these models.

Deciding specification: 280 W ATX output

The single figure that decides fitment is the 280 W ATX rating matched to the supported ThinkCentre range. Verify your system appears in the compatibility list before ordering.

The supply is designed for ThinkCentre A57, A61, A62, M55, M55e, M55p, M57, M57e and the M58P and M90P models.

Will the 280 W ATX unit fit and power a legacy ThinkCentre M55 chassis that I plan to keep?
