Most data center server racks are not currently powered this way, but with the advent of servers on the market that can operate with either AC or DC, it is possible to use the DC powering approach, thus eliminating extra power conversion steps and losses.
Server rack power systems combine robust infrastructure with intelligent management. From redundant PDUs to AI-optimized UPS, modern solutions ensure 99.99% uptime while cutting energy waste. As rack densities escalate toward 50kW+, innovations like direct DC microgrids and modular power shelves are redefining data center efficiency standards.
Rackmount servers and switches are normally repackaged versions of equipment that all contain a power supply unit (PSU), also called a switch-mode power supply (SMPS) which is essentially a rectifier that takes mains AC power, and converts it to DC to power the internals of the systems.
For instance, power supply firm Advanced Energy welcomed the inclusion of 48V power shelves: "Traditionally, data center racks have used 12V power shelves, but higher performance compute and storage platforms demand more power, which results in very high current.
