Works with my Synology 918+
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 👍🤞

Power Supply failed almost exactly 3 years from purchase
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.

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.

Didn't last long.
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.
