Description
Does your computer no longer recognise your WD My Book Essential, and does the light stay off? Then you can no longer get to the files on it. Often it isn’t the drive itself, but the adapter that no longer delivers enough power. This power supply gives your My Book Essential the 12V and 3A (36W) it needs again. Plug it in and your drive shows up on your computer again.

How to verify this is the right power supply
Check the label on your original WD adapter. It should read Output: 12V DC ⎓ 3A with a center-positive polarity symbol. The barrel connector measures 5.5 × 2.1/2.5 mm barrel (combi plug). If your adapter shows different values, it is not the right model.
Frequently asked questions
Which power supply does the WD My Book Essential use?
The My Book Essential is powered by an external 12V DC adapter (36W). The original WD adapter can be replaced by any 12V DC adapter with the same barrel connector, correct polarity and at least the same wattage. The required connector is 5.5 × 2.1/2.5 mm barrel (combi plug), polarity center-positive.
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 WD 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 WD.
