HPE Common Slot (CS) Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HPE server and storage solutions. The Hewlett Packard Enterprise 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.

High efficiency options rated for up to 94% (Platinum/Platinum Plus) and up to 96% (Titanium) power efficiency are available in the Common Slot form factor. Most options also support HPE Power Discovery Services via embedded power line communication (PLC) technology. This feature enables each server to communicate identification, location, and power-related data to the Intelligent Power Distribution Unit in the rack which can then be shared with HPE Insight Control to manage power usage and efficiency in the data center.
