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!

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***E on 21 November 2024* 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.

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. ## Frequently Bought Together - 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 - KFD 12V 10A AC Adapter for Synology NAS DiskStation DS1520+ Charger DS1522+ DS916+ DS918+ DS920+ DS923+ DS723+ DS420+ DS423+ DS620slim DS720+ DS418 DS718+ DS1019+ NAS Server Power Supply Cord Cable - Seagate IronWolf 8TB NAS Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache for RAID Network Attached Storage – Frustration Free Packaging (ST8000VNZ04/N004) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/559804217-4-pin-12v-8-33a-9a-power-adapter-for-synology](https://www.desertcart.co.th/products/559804217-4-pin-12v-8-33a-9a-power-adapter-for-synology) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
