12V 7A 84W AC Adapter with 5.5×2.5 mm Plug

This 84 W power supply delivers 12 V at 7 A and accepts a 100-240 V 50-60 Hz input. The barrel connector measures 5.5 mm outer diameter by 2.5 mm inner diameter and also fits 5.5×2.1 mm sockets. It carries CE certification and ships with a detachable power cord.

For QNAP TS-212 and TS-259 Owners

The adapter matches the original FSP084-DMBA1, FSP084-DMAA1 and FSP084-DIBAN2 part numbers used in those NAS units. Buyers who need a different voltage, a higher current rating or a connector size not listed here should look at another model.

Plug-and-Play Replacement

Installation is limited to connecting the IEC cord to the brick and the barrel plug to the device. The most common issue is selecting the wrong tip polarity or diameter, so verify the 5.5×2.5 mm requirement before ordering.

Questions about this item

Does my QNAP TS-212 or TS-259 need anything besides this 5.5x2.5mm plug to run from the 84W adapter?

No, the 12V 7A output matches the original FSP084-DMBA1 specification, and the barrel fits both 5.5x2.5mm and 5.5x2.1mm jacks.

Can I keep my existing EU, US, UK or AU power cord with this 100-240V 50-60Hz input unit?

Yes, the IEC inlet accepts standard cords for any of those regions, so the adapter works worldwide without a voltage switch.

How do I confirm the 12V 7A 84W output is stable after connecting it to my TS-259?

The NAS should power on normally, show no low-voltage alerts in its management interface, and run continuously under load without unexpected shutdowns.
