If the power supply has been in use for some time, it will likely have accumulated a lot of dust inside it. Do your best to remove dust using a brush and compressed air (the air hose at the gas station works well), but do not remove the cover from the power supply. Whether the case is new or old, check it thoroughly for sharp edges and burrs and file down any you find. That saves a lot of bloodshed later. Once the case is clean, dry, and defanged, proceed as follows:
