It came with a 3 pin cable and the PSU only had 2 pins so I didn't try to buy the green and white labeled box for the x-360. slim, for this reason I buy the one that had a different description. Luckily I was able to find another power cord for the 2-pin power supply. To look at the power block and see that it is two-pronged, not three-pronged, no special knowledge is required!
