on black friday, walmart had a huge discount on the xbox consoles , thus i bought one for my brother, and i noticed that the 250 gb xbox slim had a 120w, powerbrick, and mine had 130w, i was just hoping if i can exchange it from the one he has towards mine, Would it still function? Be better? cuz mine’s makes a loud noise and 120w doesnt. MY BRO is AN A$$Ho13.!! btw.
