A Supercomputer is not a portable machine but a great network of tons of computers interconnected to each other. Supercomputers are so big that they can cover dozens of rooms or several big halls. Some could be so big that it requires a large football to set up them. Considering the size, Supercomputers require a massive amount of power to operate. Most Supercomputers consume multiple megawatts of power for operations. Take Tianhe-1 for instance, it takes 4.4 megawatts to work.
