PRODUCT OVERVIEW

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. CS power supplies are available in multiple high-efficiency 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.<br><br>A key part of the HP Thermal Discovery Services, CS Power Supplies provide the IT industry’s highest level of power efficiency(up to 96%), helping customers to reduce power requirements by up to 60W per server and reducing overall data center power requirements by up to 10% (as compared to ProLiant G6 power estimates).

CS Platinum Plus, and Titanium power supplies also enable HP Power Discovery Services which focus on increasing compute density while reducing data center outages. This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 6130-01-569-9698, indicating validated use in U.S. government and defense logistics supply chains.
