    2.0 out of 5 stars "New" card was used and defective
    Reviewed in the United States on October 26, 2022
    Verified Purchase
    The card was marked as "new" in the Amazon listing. When it showed up it has no original packaging and clear marks from previous installation. It was authentic, but over 10 years old. I was OK with this initially, but then multiple installs and tests later I was able to confirm the BIOS will not even come up with the card installed. Seems like a dud that was removed from a server after extensive use. These guys don't pay much attention to what they are selling. Returns through Amazon are easy enough.
