KFD 4 PIN Adapter Compatible With Synology DiskStation 4-Bay DS412 DS413 DS414 DS415 DS710 DS712 DS416 DS416j Ds416play DS416SLIM DS418 DS418j NAS Server Diskless Network Attached Storage Power Supply

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

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

This power adapter died after 6 months.

Not for the DS416slim as advertised.

So far so good!

Smoked up upon first plugging in then cord kinda melted. Wouldn’t recommend buying, you can find smoke bombs for much cheaper.

looks to be high quality item hope it will stand the test of time

Synology DS918+, works like a charm!!

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.

My Synology was randomly powering off for unknown reasons and then, one day, decided to turn off and never come back. I suspected the power adapter immediately and jumped onto Amazon to order this replacement. While the connector to the back of the Synology was a bit tighter than the OEM, it went in fine and as soon as I connected the power, my Synology came back to life! While its too early to tell about longevity, this adapter feels very solid and should last for at least as long as the original (5 years).
