Bought used about a year ago, mining since. Never had any issues.

Moved out of my old place, and don't have what I need to keep my crypto mining farm operational (220V power and a second bedroom... lol). Selling off additional cards. (If anyone is interested in 2x 12GPU Octominer's w/ 3300W 220V only PSU's feel free to send a message. Pickup in SW Chicago suburbs only for the octominers. $1000 for both)
