External PSU’s can help keep that heat away from the most valuable pieces of your system. Perhaps the most convenient thing about external power supplies is that they are far easier to replace than any other kind of power supply. If the internal power supply fails, to put it plainly, you are in trouble.
A standalone external power supply supplies power outside the main enclosure of an electronic device. It converts AC power from a wall outlet into the DC voltage that the electronic device requires. It is also known as power converters or wall warts.
The only way to pull this off is to have the power generation brick on the outside, and then a box that splits it all out on the inside. In which case now instead of having one internal box, you now have the same internal box AND an external box. In short it would be a HUGE step backwards to make a PC power supply external.
