Review: Power brick saved my data! - 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!
Review: Fixes the issue if its the power brick - 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.

## Questions & Answers

**Q: Does anyone know what the pinout is?**
A: I tore apart the one that failed on me (Synology original), and it turns out that the brick has only one output: +12 (I presume, haven't measured a running one) and GND. Testing continuity on the cable itself shows that if you hold the connector facing you, with the notch on top (where the arrow lines up) the two top pins (the ones slightly farther apart) are VCC, and the two lower (and the metal casing) is GND.

This is all empirical information dissecting the blown up one that I replaced, but I'm not an electronics engineer by any measure, so take it with a grain of salt.

**Q: Does this power output 5V and 12V?**
A: No I don't think it does it's marked output is 12

**Q: Will this work with a Kodak i1420 Scanner?**
A: I cannot correctly answer your question. If it takes the same connection it should work. But I cannot say for sure that it will work

**Q: Will this work for a LaCie Big 5 hard drive**
A: check the model list on this one. https://www.amazon.com/T-Power-Adapter-Compatible-ACU034A-0512-ACU057A-0512/dp/B00PXCV9AU/ref=sr_1_3?crid=2VUT6NF1F19HE&keywords=LaCie+Big+5+hard+drive+power+supply&qid=1668091870&sprefix=lacie+big+5+hard+drive+power+supply%2Caps%2C109&sr=8-3

### ⭐ Lost a 10TB WD Red Pro HDD
*by J***N on February 3, 2026*

Purchased this on 05/06/2024, and it died on 02/02/2026, connected to my Synology DS918+ NAS, and lost a WD Red Pro 10TB drive because of it. Thankfully, I'm running RAID5 and can swap in a new drive, but now I'm out $250+ for a new drive thanks to this thing failing. The power failure caused 2 drives to have issues (one entering Critical condition and another needing me to Repair System Partition). Thankfully, I saved one of the drives, but the other is dead in the water. I use a heavy-duty backup battery 600VA UPS, which was connected to as well, so it's not like there was a surge or power failure that caused anything else to happen. My recommendation: Buy a better brand and/or OEM external power supply for your NAS if the OEM dies.
