## Long description

HP Common Slot (CS) Power Supplies are designed for hot-swap, tool-less installation in HP servers and storage systems. They follow a common electrical and physical design that enables compatibility across compatible HP platforms and are offered in multiple high-efficiency input and output variants so customers can choose the appropriate power capacity for specific server and storage configurations.
Advantages
CS power supplies allow right-sizing of power to reduce wasted capacity and lower energy costs. With efficiency up to 96%, they can reduce server power requirements by up to 60 W per server and lower overall data center power consumption by up to 10% compared with prior-generation ProLiant G6 estimates. Platinum Plus and Titanium models support additional HP Power Discovery Services to help increase compute density and reduce the risk of data center outages.
