Supermicro PWS-2K04A-1R 2000W server power supply

Server power supply for redundant deployments

The Supermicro PWS-2K04A-1R is a 2000W redundant server power supply built for high-availability environments. It suits data-centre racks and critical workloads where continuous uptime is essential. It is not for desktop builds or single-unit installations that do not require redundancy.

2000W capacity with Titanium efficiency

At 200-240V input the unit delivers the full 2000W with 80 Plus Titanium efficiency, keeping waste heat low under sustained load. At 100-127V the same hardware is limited by the 12A input rating, so maximum output drops accordingly. Workloads that exceed the available input current will hit the protection limit.

1U redundant form factor with PMBus 1.2

The 1U redundant design enables hot-swap replacement in compatible Supermicro chassis without powering down the server. PMBus 1.2 provides monitoring of voltage, current and temperature for remote management. Buyers without a matching redundant backplane cannot use the hot-swap or monitoring features.
