I replaced my old PSU With a new one and RMAed the old one and I was sent this as a replacement. Since the new one I purchased is better than the replacement they sent me I'm going to sell this one. It cost me over $30 in shipping expenses to RMA it so you are really only paying $50 for the PSU. As you can see in the pictures it still has the plastic wrap on it as I haven't even opened the box, its completely brand new.
