The input of the Arise supply is protected via a fuse and diode if I remember correctly, so I doubt you killed it. Someone with electronics knowledge will be able to determine the problem in a few minutes, but a blown fuse is fairly obvious. If I remember correctly, the diode is reverse biased in normal operation, and there is a fuse in series with +. When things are connected backwords, the diode is forward biased and conducts large currents and thus the fuse blows....but I could be thinking of something else. Best to have someone check it...or post some really good close up pictures of the input half of the supply.
