Replacement power for 3 TB desktop drive

This BASEUS AC adapter supplies 12 V at 1.5 A to the STEG3000100 Expansion Plus 3 TB hard drive. It replaces a lost or faulty original unit so the drive can spin up and transfer data again. The adapter accepts 100-240 V AC at 50/60 Hz for worldwide mains compatibility.

When the original supply fails

Swap to this unit when the factory brick no longer delivers stable voltage or the connector is damaged. The jump is worth it if the drive itself is still healthy and only the power source needs renewal. Built-in over-voltage, over-current and short-circuit protection guards the drive during the changeover.

Limits of the barrel-connector interface

The fixed 12 V output suits only devices rated for that voltage and a 1.5 A draw. It cannot power drives requiring higher current or a different voltage rail. Polarity and plug dimensions must match the drive’s input jack exactly or the connection will not work.

Questions about this item

What AC input voltage range does the 12 V 1.5 A adapter accept?

The adapter operates on a worldwide input of 100-240 VAC at 50/60 Hz, so it works on mains supplies in most countries without a voltage converter.

How do I connect the adapter to the STEG3000100 Expansion Plus 3 TB drive?

Plug the DC output cord into the drive's power jack and the AC plug into a wall socket; the step users sometimes miss is ensuring the barrel connector is fully seated before powering on.

When should I consider replacing this power supply?

Replace the unit if the drive fails to spin up, the adapter becomes unusually hot, or the output voltage drifts away from 12 VDC under load.
