HP Common Slot (CS) Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HP server and storage solutions. HP's CS power supplies offer high-efficiency power options available in multiple input and output options, allowing users to "right-size" a power supply for specific server/storage configurations and environments. This flexibility helps to minimize power waste, lower overall energy costs, and avoid "trapped" power capacity in the data center.
