PWS-1K30D-1R Supermicro Active 1300W 1U Server PSU

High-Density 1U Redundant DC Power Module for -48V Racks with the PWS-1K30D-1R

The PWS-1K30D-1R is a 1300W 1U redundant DC power supply module engineered for modern -48V nominal DC bus data centre power architectures, enabling predictable power standardisation across uptime-focused racks. Designed as a hot-swap class PSU building block in redundant configurations, it supports stable power delivery for CPU-dense platforms and GPU-accelerated nodes where continuous operation and controlled power domains are mandatory.

Within DC-fed infrastructure, the PWS-1K30D-1R accepts a wide -44V to -65V input range to maintain service continuity through bus fluctuations and load transitions. PMBus 1.2 telemetry integrates with platform management for visibility into power states, efficiency, and fault conditions, which is critical when managing high PCIe expansion densities and mixed NVMe/SAS storage topologies. With 92% peak efficiency, the module reduces conversion losses in constrained 1U thermal envelopes. Fixed, non-modular cabling favors repeatable installs and minimizes connector variability during fleet refresh cycles.

Why Choose the PWS-1K30D-1R?

The PWS-1K30D-1R aligns with redundancy-first power designs, delivering a strong density-to-output ratio in 1U while supporting consistent operational behavior across identical nodes. It is suited to scalable deployments where PSU interchangeability, predictable DC characteristics, and remote monitoring are essential to maintaining service levels and simplifying spares strategy.

Supermicro designs power modules to match enterprise rack standards, emphasizing electrical protection and serviceability for continuous operation. The PWS-1K30D-1R includes OCP, OVP, and SCP safeguards to help isolate faults, protect downstream components, and support maintenance procedures aligned with data centre change-control requirements.

Key Applications:

• -48V DC bus data centre racks
• 1U server PSU replacement standardisation
• Redundant power domains for HPC clusters
• AI and GPU compute nodes with high availability
• Edge micro-data centres with DC distribution
