QNAP 120W 4-Pin External Power Adapter

The QNAP PWR-ADAPTER-120W-A01 is an external 120 watt power supply created for the QNAP TS-653B six-bay NAS enclosure. It delivers the consistent current that a data-heavy system needs, whether you are running business backups overnight or streaming media at home.

This adapter accepts any standard AC input from 100 to 240 volts at 50 or 60 hertz, so it works reliably in offices, server rooms, and remote sites around the world. A secure four-pin connector locks into the NAS chassis, protecting against accidental disconnects and voltage drops that could interrupt drives during critical transfers.

Keep one unit on your primary NAS and store a second as a spare. Swapping it in takes only moments, allowing you to restore power without shutting down users or workflows. Its housing is compact and finished in black, so it tucks neatly behind a rack, on a desktop, or inside a travel toolkit for field support.
