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

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. :D I'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!

Update: The seller very promptly offered to replace the power supply after submitting a warranty claim! Top marks for customer service!! Five stars for the CS team :) This power supply has been working great in my Synology DS918 since purchase 3 years ago. I received an abrupt message about unstable power supply within DSM and across all 4 drives. Upon rebooting, the system would not spin up the drives. Researching online, this is a problem when not having enough amperage to spin the drives up, Synology just sort of hangs because it cant boot the OS which are stored on the drives. I have never used a warranty for anything purchased off of Amazon, but I am reaching out to the seller to see if they will honor the 3-year warranty they claim. I will update this review upon hearing back from them.

I bought this product to power up my Synology DS415+ in Jul 2022. It worked flawlessly for 1,5 years and gave up on 31Dec2023. All my disks all of a sudden started giving errors and NAS would endlessly beep. After sometime troubleshooting when I powered my NAS up with a computer power supply and came right back up it was clear that this power supply was causing the issue. I wouldn't recommend this product.

About 4 years ago, in 2020, I bought a DS420+ to replace my aging 2-bay Synology NAS. One day, I found that it was powered off and I couldn't power it on. In my attempt to troubleshoot it, I decided to give a replacement power supply a shot. This power supply was able to power it on, indicating that the original Synology branded power supply had gone bad after 4 years of flawless operation. If you run into a similar situation where you need a replacement power supply for your Synology NAS, look no further. This appears to be a quality product that works just like the original Synology power supply.

had my synology ds918+ go offline while at a camp and when I came home, it was just off. my desktops were on, modem/router were on (both modem/router and nas are on a PSU, my one desktop that is not was still on, so not a power outage or it would be offline). Tried it on a different outlet, nothing. Pulled drives out, pulled extra ram out, nothing. Tested with multimeter and couldn't get any signal through it. one 2 of the prongs, the continuity test worked, but also noticed the green led light (didn't realize it had one) was off on the brick. Synology support said it was out of warrenty so no help there (not their issue really), so I decided to order one of these to rule that out. Came 2 days later, and when i plugged it in, green light on brick, hooked it into the nas and blue power light came on. Minute later, could connect to it. Not too bad of a fix cost after 4 years of non stop running. Might as well try that if you are getting the same thing with zero power coming, or your power brick is flickering.

Works with my Synology DS 918+. Not really much else to say. It's a power adapter

Works well. I did have one die but the company replaced via warranty. Very nice.

Purchased Jan 2022, died Jan 2024. It worked great while it lasted! But yeah, not a long term solution I suppose. When it had died the DS918+ wouldn’t fully boot, and there was a high pitched squealing sound. New power supply fixed everything for me.

It's pricier than I'd like for a 3rd-party no-name sketchy power supply :). But it worked! My Synology power adapter conked out and this one has been working for several months now without a glitch. No funny noises, no complaints. I'm not an electrical engineer so I cannot vouch it's not doing some subtle damage through sketchy voltage or insufficient current or whatever, but... so far it works 👍🤞

So far so good one month in, ordered Dec 2025.

Évitez cet article. Comme plusieurs utilisateurs, l'alimentation a lâché au bout de 3 ans chez moi. J'espère que je n'ai pas perdu mes données.

I got this as a replacement power supply for my DS918+ after the PSU started making clicking noises and couldn't boot the NAS. I plugged this in and it worked like a charm. Build quality is good.

Works perfectly and is a slight upgrade for my DS414
