Refurbished GPU’s are not always cards that failed. Refurbished GPU’s can also be cards that people used for step up, and when that is accomplished, the card was typically in full working order when it was sent back to EVGA.
I would suggest contacting EVGA directly at
support@evga.com, or through your original ticket, and speak with them. As users of the forum, all we can do is answer your question.
As for the resale comment, 99% of users asking about the original box are wanting to keep it for resale purposes. If you aren’t in the 1%, then it doesn’t apply to you and was just a general comment.
