OEM items are brand new, but they’re meant for experienced users and system builders.
They don’t come with retail packaging, accessories or manuals, although documentation and software can typically be downloaded from the manufacturer’s website.
Important:OEM items come in a plain box or plastic bag (bare card or bare drive packaging) with little to no documents or instructions. This is also why OEM software is non-refundable – there is no retail packaging to hide the serial number or key code.
