So, you dug out your old 500GB Western Digital My Book Essential, but you can't find the power brick anywhere?

Yeah, happens all the time.
Don't worry, this is the exact replacement you need.

It's a brand new AC/DC power adapter from Monster Parts.
Just plug it into the wall and into your drive, and you're back in business.

No more drives clicking sadly because they're not getting power.

This is specifically made for those WD My Book Essential enclosures, so it matches the voltage and connector size perfectly.
It's a home charger type adapter, meaning it's just the basic wall wart to get your drive spinning.

The MPN is listed as 'Power Supply Cord Wall Charger,' and it comes with the UPC 603827779137.
It's new in the box, or at least in its original packaging, so you know it hasn't been banged around.
It's a straightforward part—no setup, no drivers, just plug it in and listen for that beautiful hum.

Perfect for recovering old photos or files from that backup you forgot about.
