Our DS412 died (power supply dead). This is an exact replacement and came quickly. Our life is on that NAS. So thankful it came so quick.

My old plug failed. I bought this to replace it and my ds418play started right up

This power adapter died after 6 months.

This power adapter died after 6 months.

I bought a used Synology NAS and the power adapter was missing. This served my purpose of getting the Synology DS916+ up and running.

My Synology DS916+ was suddenly powered off and I quickly determined that it was because of a dead power supply. Ordered this one which arrived the same day and all was well after replacement.

My DS918+ power brick died after just under five years of use, and this one works perfectly as a replacement. Its been going for just over a week with no issues.

Update: 11 months later and power adapter still working without issues. Was about to pull the trigger on a new DS920+ as my DS918+ had the blue blinking led issue. Online documentation indicates the flashing blue led is a motherboard issue and you need to send it back to Synology for repair/replacement (if the unit is still under warranty). My unit was 6 months out of warranty. Purchased the KFD Power adapter and the NAS has been working for the past 10 days without any issues.

The original PSU for DS918+ failed after 3.5 years. This KFD 100W power supply works great as a replacement.

The adapter worked properly to power a Synology DS918+. The original OEM power supply still displayed a green light but was unable to sufficiently power the Synology to allow it to start. This replacement adapter allows the Synology to start and run properly.
