Fit my "hand me down" company computer, Optiplex 380MT (the tall tower, Late 2009). Had to do my homework to see if it would work but it fit perfectly. I took the part number off the present one (H7283 if I remember right) and compared all the connectors but mine had the "small blue tab" near the cable. The picture shows the larger one which I imagine is from one of the other part numbers? It may just be an optical illusion but I figured I could have shortened it up if I had to just in case. No problem it fit fine. There are a few different part numbers that are basically the same caddy.
