Compatible replacement adapter

This AC adapter replaces the original power supply for Seagate Backup Plus 3TB and 4TB desktop drives, models STFM3000100 and STFM4000100. It delivers the correct voltage and polarity for reliable operation with these specific external hard drives.

100 to 240 VAC input range

The unit accepts worldwide mains voltage from 100 to 240 VAC at 50 or 60 Hz, so it works across different regions without a separate converter. A ten-foot power cord provides generous reach from the wall outlet to the drive.

Safety protections and certifications

Built-in safeguards include over-current, over-voltage, short-circuit and total-power protection, plus a smart chip for overheating prevention. The adapter carries FCC, CE and RoHS certifications and uses high-quality materials for durability.

Questions about this item

Will this adapter run my Seagate Backup Plus 3TB STFM3000100 alongside my older USB 2.0 hub?

The adapter supplies the exact voltage and current the STFM3000100 needs, so the drive will spin up normally even when other legacy USB devices share the same host.

How can I verify the unit is delivering stable power after I plug it in?

The drive LED should stay solid and the enclosure fan, if present, should run without cycling; the adapter’s over-voltage, over-current and short-circuit protections engage automatically if anything drifts out of spec.

What ships in the box and what must I source separately?

The package contains the AC/DC power brick with a 10 ft cord and the detachable mains lead; no drive, data cable or mounting hardware is included.
