Are you drunk or what? You asking about plug on your PSU but you post picture of your power cable.
BRO, JUST BECAUSE HE USES CAPS LOCK AND MAKES NO SENSE DOESNT MEAN HES DRUNK
1) NEMA 15 is the plug that goes into a 110V socket.
2) nema 13 is the plug end shown in the picture
3) nema 14 is the receptacle on the PSU. It is the same receptacle on virtually every single ATX power supply, with the rare exception of a nema 20 for heavy duty 220V
4) he took a picture of the cord, which is 100% compatible witht he described power supplies.
@OP: connect the cord end you took a photo of to the receptacle (its a similar-shaped hole on the PSU). The other end of the cord fits a socket on the wall with a similar shape.
