It works

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.

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.

Works on my Synology DS918+.

Original went bad and couldnt find an OEM replacement. This one did the job

This power adapter died after 6 months.

Dreaded flashing blue light on my DS918+. Unit would boot up without any drives and also with a 2.5 SSD so motherboard looked ok. But as soon as any 3.5 drive was inserted the unit would fail to start successfully and reboot (when trying to power up the drive a few seconds in). Replacing the power supply with this KFD unit resolved my issue.

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

I ended up ordering this twice as my first one was DOA, leading me to question whether or not it was my machine that was dead. However, the power brick has a light on it and the first unit’s light was not lit. Using a multimeter, I could tell there was no power. The pin out is printed on the label in case you need to check. Second unit works as intended, light is lit, brought my NAS back to life
