TAIFU 4-Pin 12V 8.33A - 9A Power Adapter for Synology Disk Station 4-Bay DS410 DS410j DS411 DS411J DS412 DS412 + DS416 DS418 DS918+ DS923+ DiskStation Network Storage NAS Server 12V DC Power Supply

It's works! using this plug for my Synology Nas. only been a couple months so far. So will see how long this plug last. For now, I will give it 5 stars. It I can get 2 years of use out of it only then I will recommend it

Well, the other morning I woke up to over 800 email notifications from my 6 year old Synology DS-918+, each one stating "abnormal power" on each different drive. The final E-Mail was that Storage Pool 1 was crashed. And here I thought having a one drive fault tolerance would be good enough to protect 30 years worth of documents, photos, music, and movies. If one fails then I'll just throw a new drive in, rebuild the array, and carry on. How wrong I was.It wasn't until I actually started think about what was actually irreplaceably important out of all that that I started freaking out and had an anxiety/panic attack last night.And then this power brick showed up today.My NAS is currently powered up, accessible, and copying all of the important stuff to both Storage Pool 2 on the DX517 Expansion module as well as to a standalone SATA drive plugged into a different system that I'll store elsewhere.One drive is "crashed" and in read-only mode. Fine, fine. I'll take it out, format it in a different system, replace it, and rebuild the array. The other one has a "System Partition Failed". Ok on that one too...that's a future problem to resolve. All drives report Healthy, so that's another plus...it's just the file system that has a problem.So...this purchase was worth every single penny and saved my sanity. I'm not sure what I'm going to do with all of the stock in Tums that I just purchased though. :DI've also got a new-open-box DS-920+ on the way. I'll throw 4 of my old 8TB drives in it, copy my data to it as well, plop it over at a friend's house, and figure out how to do remote syncing.This will not happen again!

Had my original Synology power adapter fail after a few years of use, so decided to give this one a try. It’s significantly cheaper than the Synology branded adapter, but so far it seems to work great on my DS918+. Time will tell whether it lasts longer than the original, but definitely no fitment issues and no performance issues, so I’m a happy customer.

failed after 2 years.over this last weekend, my snylogy starts complaining about disk power resets. eventually all the drives were resetting while it was online.looks like it's ability to sustain the current draw is a problem. voltage is drop during busy times while the sinology is attempting to operate.now can't even power on disk 1 and 2 (while disk 3/4 power up). the drives are in a power cycle loop. you can hear them start to spin up, then down. and 10-20 seconds later, retry. almost thought I had a double disk failure.turns out replacing THIS power supply with an official Synology power supply fixed the issue.BEWARE - if your data is important, always back it up somewhere regardless. but also avoid this power supply for the needless restore from backups when it eventually can't handle the current draw.

Woke up one morning to my Diskstation being offline. It had been doing that lately about one a month but I couldn't figure out why, there were no logs and it was on a UPS. So, I went and hit the power button and it whirred up, lights came on, disks clicked and then - off again. I checked the plugs, made sure things were snug and hit the button again, this time it didn't even get as far as the previous time.The unit was six days out of warranty.My AMEX card gave a 1 year extended warranty but required an estimate to repair - Synology would not provide the estimate since they don't make that one anymore. My local PC repair shop wouldn't quote on it. So, out of luck.Searching around online I found a few things it could be. Replacing the power supply was the easiest (others required me to do some soldering on the board) but since it wasn't a sure thing I decided to go with this no-brand power supply. It did the trick and one year on it's still going strong. So if you have a DS418Play and it starts shutting down this might be the fix you're looking for.

worked 2 years and gave up

The power supply for my DS918+ failed after a storm & power outage. This replacement is working perfectly so far!

Purchased this power supply when I came home one day to find my Synology DS918+ NAS powered off. Confirmed the power light on the external power supply to remain off when plugged in. Replacement arrived within 48 hours and powered on my NAS without any issues.
