Synology Power Supply

My Synology DS1019+ power supply died after two years (thanks Synology), even though connected behind a double conversion UPS, so it's not a question of power quality. This one was available same day, and works great, so it got me back to work quickly.

Shortly after my Synology DS1019+'s 3 year warranty expired, the OEM power supply failed and caused the dreaded Blue Blink of Death. The OEM power supply LED also went dim as my DS1019+ tried to power up, even with no drives inserted.After looking into replacement options, this power supply seemed like a high quality product with output specs identical to the OEM power supply (12V DC at up to 10A). The fact that Synology lumps DS1019+ and DS1520+ replacement power supplies together (what they call "120W Level VI") gave me further confidence this power supply was compatible, for about 60% of the cost as other options.And sure enough, this power supply revived my DS1019+ and all data has been validated!

Orig power suppy failed; this came quickly and is working well. Recommended.

Another garbage power supply - bought in Feb, power supply and NAS dead again by Sep.

It works

Purchased for my DS918+ to replace KFD EA11001E-120 which died just past the 36 month warranty. (My original Synology OEM power supply only lasted 30 months.) NAS started right up and power supply is running cool connected to my UPS. Preliminary 5 Stars. Will update when this joins the scrap heap. Thumbs up for the free prime overnight delivery. Ordered yesterday afternoon, was at my doorstep when I woke up this morning.

When my Synology DS1019+ failed to boot, I thought I would need a new RAID unit. (I was confident that the data would be there when I plugged the disks back in if I inserted them in the same order). But I continued troubleshooting.Troubleshooting - I noticed a faint buzzing noise which I tracked down to the power brick and the fact that the power button did not light up made me suspect that the problem could be the power brick rather than the Synology disk unit. When the shipment arrived, I was pleased to find that this was the case. This power supply worked perfectly as a replacement for the original.Update Mar 2025- It failed after just under 2yrs, at the same time as my UPS powered off for a failed battery. Perhaps the UPS was partially to blame.

product reviewed: KFD 12V 10A AC AdapterA friend gave me their fully-loaded QNAP TVS-951X with a Netgear AC adapter (original blew very soon after purchase). I noticed it was trippin', so I compared Netgear AC adapter specs to NAS requirements... yep- NAS needs 10A whereas Netgear AC adapter was 7A. I'll bet it was trippin' for my friend and didn't even know it. Bought this AC adapter, plugged it in and my NAS hasn't tripped since (it's been over 4 months). Green LED in upper right/lower left to indicate AC adapter is merrily converting AC voltage to DC. Happy with purchase.
