So I asked one of the Corsair Q.A. engineers about this a while back. They said they mark the connectors with magic marker to show that they were tested for pin to pin compatibility. No markings mean the cables weren't tested, so they don't pack them until they're tested.
Which model in particular is this? While I'm not concerned about the magic marker markings, I am concerned with how dirty the cables look and why there's white stuff all over the connector.
