⚠ Always match voltage (12V DC) and polarity exactly. A higher amperage rating is safe; a different voltage is not.

Important before you buy

Never use a 19V laptop charger. Marketplace listings offering "19V" adapters for this NAS are mislabelled — 19V destroys the device. Use 12V only.
The 4-pin DIN pinout differs between brands. Only use a Synology-specific power supply — a 4-pin adapter from another brand can damage the device.

How to verify this is the right power supply

Check the label on your original Synology adapter. It should read Output: 12V DC ⎓ 8.33A with a center-positive polarity symbol. The barrel connector measures 4-pin DIN (Kycon KPPX-4P). If your adapter shows different values, it is not the right model.

Frequently asked questions

Which power supply does the Synology DS923+ use?

The DS923+ is powered by an external 12V DC adapter (100W). The original Synology adapter can be replaced by any 12V DC adapter with the same barrel connector, correct polarity and at least the same wattage.

Can I use a power supply with a higher amperage rating?

Yes. The device only draws the current it needs. A higher amperage rating is safe. Never use a higher voltage.

Is this an original Synology power supply?

This is a compatible replacement adapter that meets or exceeds the original specifications, is CE-certified and tested before shipping. It is not manufactured by Synology.
