Unless you tested the seemingly broken SATA port your Samsung SSD was using during the first power failure (which you did not mention doing), you cannot yet conclude that the SATA port is truly broken.
An OS drive that loses power when it is in use tends to become stuck or frozen, since it is usually performing an I/O operation. Storage drives are just idling along, or may have even gone to sleep, depending on your settings in the OS.
I doubt any of the SATA ports are no longer working. Switching the SSD to another port just gave it a fresh start, after a more normal powering down, via the power button.
Was the SSD on an Intel SATA port, or the ASMedia SATA ports during the first power loss? A power loss is different than a power surge or spike due to lightning, so nothing was damaged.
I've never had a board damaged by a power loss.
