Spare power provide

Found much commonly in servers and other high-end computers, a redundant power supply contains 2 (whether more) power supply units inside it. Each power supply is capable of powering the entire computer and only one runs at a time. Provided 1 fails, the other power provide starts moving to keep the computer powered up. The switch between the power supplies is seamless, so as not to disturb the normal use of the computer. Within the picture to the right, is an example of what a redundant rule supply may look like.
