Anyone know what the name of the square 12v PSU plug that goes into some motherboards is called? Just Im looking to buy one but not sure what its called. Also does anyone know what v wires go where in this plug? Ive got an old PSU which Im wanting to use but it doesnt have this 12v plug on it so my idea is to just chop one of the molexs off and rewire to this new square plug. Anyone know if thats possible? Not sure if this should be in modding Cheers.
