I had a 918+ that just... died. It started and then stopped, didn't POST.
Panicked, built a full-ass Fractal 804 case + Unraid setup to replace it.
Was looking around for That Guy who mails around a Synology box so I could get my data out and stumbled on a forum post(!) that said the external PSU just fails subtly sometimes. It gives enough power to start booting and then fails.
Bought a 3rd party PSU from Amazon and the Synology boots up.
Now the 918+ lives as an off site backup at my parents' house =)
