Remote Power Distribution Unit (RPDU) (1 of 17) lead to multiple system failures. After lengthy discussion with Dispatch; Maintenance Control and the duty manager; we determined to continue the flight to our destination due to system redundancies.  One of the failures was an APU fuel valve failure which lead to the APU not being able to be used if necessary.  Multiple status messages were displayed and discussed with Maintenance to include going into the maintenance pages to ensure operational systems for later use in the flight. Upon landing and parking at the gate; the flying pilot (First officer) attempted to shut down the left engine while keeping the right engine running while ground power was connected.  The engine did not shut down with the fuel cut off switch (initially) and we got an EICAS message to run the ENGINE FUEL VALVE FAILURE Checklist.  The checklist directed us to wait 20 seconds - we did and then the engine shut itself down.  At no point after the RPDU electrical failure did we expect it would lead to an engine fuel valve failure.  The rest of the parking and termination checklist was normal.
