OWC Mercury Elite/Neptune Power Adapter

5.0Amp Barrel Style Power Adapter

This power adapter is for certain OWC Mercury Elite Pro storage solutions and enclosures with a DC 12V power input accepting a barrel type connector.

This power adapter is NOT compatible with 4 or 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 Power adapter accepting a 4, or 5 pin style connector.

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.

For 4-pin connection power, we recommend the OWC 4-Pin Power Adapter.
For 5-pin connection power, we recommend the OWC 5-Pin Power Adapter.

Note: This part includes the transformer to device portion of the power supply only. Power cords sold separately.
