Review: Power supply for Synology, buy at least 2! - Nothing is worst than having your NAS die due to a faulty power adapter. I have a 4-bay Synology for several years now, and it is solid hardware. The first time the factory power adapter failed, it just shut down and didn't start, thus it was easy to diagnose. I got the power adapter replaced and it worked fine again. But recently the DSM tells me there's degradation on one of the disks (I only use NAS-rated hard drives). Then a second disk started reporting problems. I didn't realize it was the adapter that was starting to fail. I replaced the hard drives (at a huge expense, let me add), but the problem persisted. So I ordered two of these adapters, because I cannot afford down time. They last long and they aren't expensive considering their importance. After replacing the faulty adapter everything has been working well. Any future glitches, and I will just swap the power adapter with the spare I have sitting there waiting to save the day. It's been working great so far.
Review: Perfect fit for DS918+ - I recently purchased this AC adapter to replace the faulty one that came with my Synology 918+, and I couldn’t be happier with the result. I was experiencing the blinking light issue, which I found out meant my original adapter was no longer working properly. After a bit of research, I decided to go with this adapter, and it solved the problem completely. The installation was straightforward, and once I plugged it in, the blinking light issue immediately disappeared. It’s been a couple of weeks now, and the adapter has been working perfectly with my Synology NAS without any issues. The device is powering on consistently, and I’ve had no problems since the replacement. If you're dealing with the blinking light issue and need a reliable replacement, I highly recommend this AC adapter. It worked perfectly for me, and it’s been a solid, trouble-free solution.
