The Supermicro PWS-2K05A-1R is a 1U redundant titanium power supply designed for server environments. This unit provides 2000W of power and includes PMBus support, facilitating power management and monitoring within compatible systems. Its redundant design ensures continuous operation by allowing one power supply to take over if another fails, which is critical for maintaining uptime in business-critical applications. The 1U form factor (73.5x40x265mm) makes it suitable for integration into high-density server racks where space is at a premium.
