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

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

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.

Power supply had died on my DS916+ and this fixed it.

So far so good!

Worked.

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

Worked.

So far so good!

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.

Synology DS918+, works like a charm!!
