This is an Akitio Node Thunderbolt 3 External GPU, and the reason why it's being sold is that I don't need it anymore. I used to use it for connecting an Nvidia GTX 980 Ti to my laptop, but I put that video card into a gaming PC I built instead, so I don't have to play games on the laptop anymore. It was mostly sitting around in a closet at my house for a while before deciding to sell it now, and during that time I unfortunately lost the Thunderbolt cable it came with. When I was using it back then, it worked very well and is still in great physical shape, with not having much scratches or chips of any sort. I plugged it in to make sure that it still works and receives power, just keep in mind it will be sold by itself and doesn't come with any cables or its original box at all. If you have any questions about this EGPU, please feel free to message me!
