> 3 dayMy 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).

> 3 dayOur 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.

Greater than one weekThe 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.

12-06-2025The original PSU for DS918+ failed after 3.5 years. This KFD 100W power supply works great as a replacement.
