System Board Replacement for Optiplex GX280 SFF

Can you give me the mdoel number of the latest replacement MB for the GX280 SFF?

I recently had a problem with the machine powering down or hibernating - amber light blinks on the power button.

Powers off on the BIOS screen too. I am fairly certain it is related to overheating.

Dell Y6281 is what I am seeing being offered as a replacement system board.

Is this correct?
