OWC Mercury Elite/Neptune Power Adapter

4.2Amp 4-Pin Style Power Adapter with 6' Power Cord

This power adapter is for certain OWC Mercury Elite Pro and Newer Technology Guardian MAXimus storage solutions and enclosures with a DC 12V power input accepting a 4-pin type connector.

This power adapter is NOT compatible with 5 pin plugs used with OWC Mercury Elite, OWC Mercury Elite-AL, OWC Neptune, and NewerTech miniStack storage solutions/enclosures. Those adapters require a DC 5V/12V 2A Power Input accepting a 5 pin style connector.

For 5-pin connection power, we recommend the OWC 5-Pin Power Adapter.

For your convenience, a compatibility chart is provided below to ensure proper product selection. Please be sure that your drive enclosure or router has this port before ordering.

This kit includes the transformer and single connector power cord for North American power outlets. Purchase the power transformer separately for use with multiple connector power cords or alternate country power cords.
