Rather than try to explain it here, this link will take you too a great source of the technology.
Redundant Power Supplies
One advanced feature available on high-end machines (especially servers) but also available to the general public for those willing to pay for it, is a redundant power supply. In essence, this is a power supply that actually includes two (or more) units within it, each of which is capable of powering the entire system by itself. If for some reason there is a failure in one of the units, the other one will seamlessly take over to prevent the loss of power to the PC. You can usually even replace the damaged unit without taking the machine down. This is called hot swapping, and is an essential productivity backup for use in servers and other machines used by a number of people.
Hope this helps.
