Today we take a look at the latest redundant power supply from OEM manufacturer FSP. This 500 watt unit is ideal for placement in servers or workstations within small business environments. The Twins 500W power supply actually incorporates two 520 watt supplies inside an outer ATX sized shell.

When the power supply is operating normally, each of the units shares the load, with the fall back option that if one fails then the other can take the full load ? without any down time. The redundant. hot swappable concept is interesting and one we don't often get the chance to investigate.
