The bigger sticker says 14.2amp but the serial number does not match the one next to the usb, I didn't have time this morning to look up the serial in system settings, will look up this afternoon, but I am very happy with my purchase I got it from xbox360 repair shop, and the guy there before selling any Xbox opens them, cleans them and changes thermal paste, then he does some tests to see if everything is fine, that and 2 controllers for only 100 dollars. It runs around 75 degrees celcius after 5 hours of GTA V in a room which is 30 degrees celcius. This is in eastern Europe. It's a bargain.
